They've known one another for years and even worked together on occasion, but Rod Stewart and Elton John's long friendship has never led to a full-fledged tour -- something Stewart would like to rectify before it's too late.

Stewart, who presented John with the inaugural Brits Icon Award on Sept. 2 before the duo performed a duet, later told reporters that he's hoping their performance is just the prelude to a whole series of live dates. "We did do a duet on one of my 'Great American Songbook' albums, but really I'd love to -- before we're both in wheelchairs -- go out and do a tour together," Stewart said. "I'd love to do that."

But John's recent admission that he'd like to cut back on touring might put a damper on any plans.

In the meantime, Stewart has a full slate of touring commitments to get through, including a run of European shows in September and a U.S. package tour with Steve Winwood in October, as well as a string of Vegas dates in between. And then there's the matter of following up his most recent LP, 'Time,' which found Stewart co-writing original material for the first time in years. Asked if he planned to keep writing, Stewart shrugged, saying, "I'm slated to do a country album. I mean, it's probably the only genre I haven't covered."
