Elton John Reveals New Collaboration During "Chelsea Lately" Appearance

Facebook.com/EltonJohnElton John made a relatively rare talk show appearance on Wednesday when he visited comic Chelsea Handler's the E! show Chelsea Lately, which this week is featuring Foo Fighters frontman Dave Grohl as guest host. During the interview, the Rocket Man revealed that last fall he contributed to a song by Queens of the Stone Age, a veteran alternative-rock group that currently features Grohl on drums.

The conversation was something of a gush-fest between John and Grohl, beginning with the two recalling how they first met.

Grohl explained that he was in London with his wife and a friend several years ago when they spotted Elton hurrying into his car. The starstruck friend wanted Grohl to introduce them, but the pop superstar's car drove off: only to stop and, to Grohl's surprise, drop John off so he could introduce himself as a fan of the Foo Fighters singer.

Elton explained his decision to appear on the E! show by saying, "I do respect this guy so much, I think he's probably the most respected guy from his generation in the business, and I couldn't say no. And I love him dearly."

The pair then discussed their until-now secret session with Queens of the Stone Age, which apparently took place immediately after John recorded a duet with British crooner Engelbert Humperdinck. "I went from Engelbert Humperdinck to Queens of the Stone Age, which was a bit of a mindf**k," joked Elton.

No word on when or if the track will see light of day, but Queens of the Stone Age have said they plan to release a new album sometime in the first half of this year.

John also revealed that he's willing to play with a lot of bands, but hardly any ask him because they assume ***** say no.

In addition, Elton expressed his admiration for Grohl, saying, "I love him because he's still a fan of music. He's got so many different projects he plays on, he's got so many bands he's a part of, and he has the time, he takes the time to champion people, and that's where I'm at, still, and I love people like this so, you know, he's a good guy."

As the interview wound down, John told Grohl, "One day, I'll play on stage with you, maybe." The rocker responded by saying, "Promise?" to which Elton replied yes.
