Billy Joel and Elton John in 'piano band'
Billy Joel says if he'd been in a band they would have split up years ago.
He says being solo for more than 30 years has had its advantages.
But his current American tour with Elton John is different.
"I was the guy. And I brought a band with me. Now let's say since 1970 I've been doing this. If I had been a band, man, I would have hated my guts. I'm one person. I can't break up," said Joel.
"When I went with Elton, it's different than just being Billy Joel. It's Billy Joel and Elton John. I get to play Elton John music.
"He plays my music. We play both our music together. I play with his band. He plays with my band. We play piano on our own. We jam. We have piano duels. It's kind of like joining a piano band."
