In an excerpt from Ken Sharp's new book Play On! Power Pop Heroes, Daltrey says: "For the My Generation album, there was nothing to be nervous about - we used to take every day as it came.

"Every day was just a gig and I think we did the recording between gigs. We did the whole album in two afternoons, and by the end of the week we were playing the stuff on stage. That's how wonderful it was in those days."

But during recording sessions for the I Can't Explain single, there was some pressure from producer Shel Talmy, who didn't think guitarist Pete Townshend's playing was up to scratch. As a result, Page was brought in to the record the track. Talmy also insisted on bringing in The Ivy League to record backing vocals.
