We’ve been reporting on the limited dates that Aerosmith has booked for this fall, mostly in South America. But who exactly will be singing lead on such classic rock staples as “Dream On,” “Love in an Elevator,” “Walk This Way” and other setlist favorites? If you assume the answer is Steven Tyler, don’t be so sure.

In a recent interview with Metal Rules that’s just surfaced, the band’s guitarist Brad Whitford – who’s busy with the resumption of his occasional side project with singer Derek St. Holmes (formerly of Ted Nugent’s band) – was asked: “With AC/DC going on tour with Axl Rose, does this open the door to Aerosmith reconsidering a short tour without Steven and possible some guest vocalist?

Whitford’s candid and surprising answer: “Absolutely, we have considered it but whether it will happen I don’t know.” Then the kicker: “I think it would be great.”

Interviewer Robert Cavuoto then followed up: “If you had a wish list, who would you like to see fronting the band?” Whitford offered a short list of Myles Kennedy (lead vocalist for Slash’s side project), Rose (though he was kidding… we think) and Sammy Hagar.

On Wednesday (5/18) to his credit, Hagar responded diplomatically on Twitter…

“I really don’t have a comment except I’m flattered, but no one can replace Steven Tyler @IamStevenT!” https://t.co/IFt4KkF7Ya
