The age-defying Rolling Stones are three dates into their Zip Code Tour, playing North American stadiums alongside the likes of one-off openers Ed Sheeran and Buddy Guy. The trek doesn't wrap until July 15, but the band is already looking to the future.

Speaking to Rolling Stone, the band hinted a follow-up album to 2005's A Bigger Bang could be in the cards. 

"Funny you should mention that," Keth Richards said. "Just last week, the word 'studio' popped up while we were rehearsing. I said, 'Well, let's find a time. I'm ready!'"

Rolling Stones Considering Playing Entire 'Sticky Fingers' Album on Tour

The Stones have released only three studio LPs since 1990, so fans shouldn't bet on new music around the corner. But judging by the positive reviews of their recent live dates, Richards and company have still "got it."

But recording new music isn't the only option for the band. They admitted a South American tour this fall is still a possibility. "We haven't etched it in stone," Mick Jagger said.

And how is the 71-year old Jagger feeling? Like a lad again! 

"I feel pretty good, actually… Sometimes at the beginning of these tours, you feel a bit achy. But I'm in good shape. It's all about avoiding being injured. You've just got to watch it and not overdo it, and you should be able to do it for a little bit longer."

Next up, the Zip Code Tour hits Dallas' AT&T Stadium tomorrow (June 6).
