In one of the biggest collaborations in music history that never happened, Bob Dylan was interested in recording an album with the Beatles and the Rolling Stones.

The revelation comes from legendary rock producer Glyn Johns, who shared the story in his new memoir Sound Man.

Johns says that Dylan was interested in making the record, but ultimately he could not make it happen.

"Dylan asked me about the Beatles album I had just finished and was very complimentary about my work with the Stones over the years," Johns writes in the book.

"Can you imagine the three greatest influences on popular music in the previous decade making an album together?"

"Keith and George thought it was fantastic," he writes. "But they would since they were both huge Dylan fans. Ringo, Charlie and Bill were amicable to the idea as long as everyone else was interested.

John didn't say a flat no, but he wasn't that interested. Paul and Mick both said absolutely not."

"Paul and Mick were probably, right," reflects Johns in hindsight. "However I would have given anything to have given it a go."
