Think they'll take their act on the road?

Billy Joel joined Jimmy Fallon on The Tonight Show Thursday, where they formed an impromptu two-man doo-wop group and performed a rendition of "The Lion Sleeps Tonight" using only an iPad app. "You're one of my all-time favorites and just to even talk to you, I get a little bit nervous," Fallon said.

The host was the first to record his vocals on the looper app. Joel joined in soon after, performing "a-weema-weh" in a variety of keys. Fallon then introduced the lyrics to the 1961 classic by The Tokens. The audience clapped in unison as The Roots backed the fast friends up from the side of the stage.

"Billy Joel! You are the greatest!" he said when the song ended. "That was fun, buddy!"

Later in the show, the music legend announced that he's getting his own radio channel on SiriusXM. Starting March 26, the program will last three months. "I guess they want me to program some music that I like to listen to and talk about what we like to listen to on the road, or what we do. I don't know. I guess I'm gonna wing it," Joel said.

The singer also explained why he performs at Madison Square Garden once a month. "We mix it up. I don't ever want to do the same show twice. We're bringing in some of the more obscure songs, but we're doing enough of the hits, songs that people know and stuff that we like to do, and we're making it up half the time," Joel said. "It's a great place. It's the best audience. It's New York. It's crazy. The room rocks when the audience starts stomping. The building is built on springs...so when you're on stage and by the end of the show the crowd is rocking, the stage goes up and down like an earthquake."
