The folks who were lucky enough to attend Big Slick Celebrity Weekend’s sold-out auction last Saturday were treated to the vocal stylings of host Jason Sudeikis and guest Will Forte belting out “Can’t Fight This Feeling.”

But on Thursday night, the rest of the world got to see and hear their heartfelt harmonies as they reprised the REO Speedwagon ballad on “The Tonight Show Starring Jimmy Fallon.”

Earlier in the show, Forte told Fallon how wonderful it was to be a part of Big Slick, which raised a record $1.3 million for the Cancer Center at Children’s Mercy. That was Forte’s birthday weekend, and he said Paul Rudd was the ringleader in getting everyone in their hotel suite to sing “Happy Birthday” not just once but 12 times in a row. Watch that part just before the 2-minute mark.

After a bit more banter with Fallon, Forte agreed to perform a song and, mysteriously, asked for a second microphone. As Forte walked over to the mic stand, the curtain behind him opened and out stepped Sudeikis, to wild applause.

The two are used to performing together: Sudeikis plays a recurring character on Forte’s Emmy-nominated apocalyptic comedy “The Last Man on Earth” on Fox.

Fallon’s show aired only a portion of their duet together. Here you can watch the full performance, which gets a bit out of hand with Fallon chiming in …

Sudeikis hosts the annual fundraiser in Kansas City along with Paul Rudd and Rob Riggle (all three grew up in Overland Park), Eric Stonestreet of KCK and David Koechner of Tipton, Mo. They invited a horde of celebrity guests to join them for softball at Kauffman Stadium, a red carpet walk and bowling at Pinstripes and the auction at Arvest Bank Theatre at the Midland downtown.
