Public TV’s “Antiques Roadshow” is one of the most prominent programs about the treasures residing in American homes. The show fuels viewers’ hopes that their odd heirlooms and esoteric collections are valuable. Even if the ephemera is revealed to be worthless, people are gratified to hear about their neighbors’ good fortune. In addition to the advance screening of “Antiques Roadshow” episodes filmed at Bartle Hall last year, the owners of objects appraised in the shows will relate their experiences.
7 p.m. Thursday. Yardley Hall, Johnson County Community College. 816-756-3580. kcpt.org. Free, RSVP required. Peter Richard Conte organ concert
Shoppers have become accustomed to being subjected to canned music. The sonic wallpaper is often loud and irritating. The people who frequent the Macy’s store in downtown Philadelphia, however, are treated to a sublime experience. The store houses the gargantuan Wanamaker Grand Court Organ, one of the world’s largest instruments. As the official organist of the Wanamaker organ since 1989, Peter Richard Conte is one of the world’s pre-eminent keyboardists. He’ll put Helzberg Hall’s acclaimed organ to the test in a program that includes works by Johann Sebastian Bach and Wolfgang Amadeus Mozart.
7 p.m. Thursday. Helzberg Hall. 816-471-0400. kcsymphony.org. $25-$35. Lavell Crawford
Lavell Crawford seems less like a celebrity and more like a best friend. His prominent television appearances include a role as Saul Goodman’s bodyguard Huell Babineaux on “Breaking Bad” and a second-place finish in the 2007 season of “Last Comic Standing.” In spite of his storied career, the St. Louis native seems entirely approachable. His hysterical routines include musings about the irrational loyalty of mothers, the absurd behavior of game show contestants, inappropriately small bathing suits on unattractive people and self-deprecating commentary about his bulky frame.
8 and 10:30 p.m. Friday, 7 and 9:30 p.m. Saturday and 7 p.m. Sunday. Kansas City Improv, 7260 N.W. 87th St. 816-759-5233. improvkc.com. $25-$30. The Sing-Off Live Tour
The revival of a cappella singing is one of the unlikeliest trends in pop culture. Once considered the domain of barbershop quartets, the form has been revived by televised vocal competitions including “The Sing-Off.” Home Free, the Minnesota-based winners of the program’s most recent season, headline the Sing-Off Live Tour. The male quintet performs a frothy version of country that evokes smooth ensembles like Rascal Flatts and the Oak Ridge Boys. VoicePlay, a whimsical group from Orlando, Fla., and Filharmonic, a Filipino-American boy band, open the show.
8 p.m. Saturday. Midland theater, 1228 Main St. 816-283-9921. midlandkc.com. $29.50-$49.50. Kathy Griffin
Kathy Griffin is a polarizing comedian. Detractors suggest her fame is directly correlated with the increasing pettiness of American culture. Griffin’s fans counter that she gives voice to people who have become tired of the deification of celebrities. Like a redheaded version of the National Enquirer, Griffin dishes dirt on stars. Her commentary on notables is viewed as heroically daring by Griffin’s admirers. But she isn’t limited to dressing down stars: She’s funniest when she turns her sharp tongue on herself and her colorful family.
8 p.m. Saturday. Uptown Theater, 3700 Broadway. 816-753-8665. uptowntheater.com. $35-$85. Sporting Kansas City vs. San Jose Earthquakes
The conclusion of last year’s Major League Soccer season was the most fulfilling professional sports event experienced by area fans in years. The high drama of the penalty kick shootout that clinched the MLS Cup for Sporting Kansas City made the December match an instant classic. The franchise hasn’t had much time to bask in its success during the busy offseason. Goalie Jimmy Nielsen, star of the epic 10-round shootout, retired. The talented Teal Bunbury was traded and homegrown star Matt Besler was named captain. Sporting Kansas City’s new look will be tested against the San Jose Earthquakes on Saturday.
7:30 p.m. Saturday. Sporting Park. sportingkc.com. 913-387-3400. $20-$250. Cindy McCain at the Dole Institute
Although he lost to Barack Obama in the presidential campaign of 2008, U.S. Sen. John McCain of Arizona remains one of the nation’s most prominent politicians. Cindy McCain, his wife of 33 years, doesn’t shy away from the spotlight either. She’s the CEO of her family’s beer distribution business and is a diligent philanthropist. Cindy McCain works to stop human trafficking, advocates for children’s health care and pushes for the removal of landmines. On Twitter, McCain posts about family life, pop culture and her work. She’ll almost certainly touch on all these topics during her lecture at the Dole Institute.
7:30 p.m. Tuesday. Dole Institute, 2350 Petefish Drive, Lawrence. 785-864-4900. doleinstitute.org. Free. Robert Jervis on U.S. foreign policy
“We give them money, but are they grateful?” Randy Newman sings in “Political Science.” “No, they’re spiteful and they’re hateful.” Robert Jervis has a substantially more nuanced perspective of American foreign policy. The Adlai E. Stevenson professor of international politics at Columbia University will share his opinions in “Why Does the U.S. Spend So Much on Security and Still Feel So Insecure? Fear, Interests and Opportunity in Contemporary American Foreign Policy.” The event is part of a lecture series from Park University.
6:30 p.m. Wednesday. Kansas City Central Library, 14 W. 10th St. park.edu. Free, registration requested. ‘Disney on Ice: Let’s Celebrate’
The timing of the “Disney on Ice: Let’s Celebrate” production at the Sprint Center is ideal. The winter-themed film “Frozen” has captivated moviegoers of all ages since its release in November. Last month’s Winter Olympics reminded viewers of the excitement and elegance of figure skating. “Disney on Ice: Let’s Celebrate” allows audiences to extend the winter-themed fun. Billed as a “colossal party on ice,” the carefully choreographed show puts skates on dozens of favorite Disney characters. Buzz Lightyear, Mickey Mouse and Ariel will be among the personalities featured at the family-friendly show.
Wednesday through March 30. Sprint Center. 816-949-7000. sprintcenter.com. $16-$55.
