The producer Glyn Johns worked with people like the Beatles, the Rolling Stones, and the Who on some of their peak-era classics. And according to Johns, he almost worked on something that could’ve been a bigger deal than any of the real albums on his résumé. In his new memoir, Sound Man, Johns claims that Bob Dylan enlisted his help in making an album with both the Beatles and the Stones. Together. Honestly, it’s probably best that the album never happened; the entire baby boom generation might’ve immediately immolated.

According to Rolling Stone, Johns writes that he encountered Dylan at a New York airport and said nice things about his work with the Beatles and Stones. And then, Johns writes, this happened:

He said he had this idea to make a record with the Beatles and the Stones. And he asked me if I would find out whether the others would be interested. I was completely bowled over. Can you imagine the three greatest influences on popular music in the previous decade making an album together?

Johns contacted all the relevant parties and tried to make it happen, but a few key parties were just not down with the idea:

Keith and George thought it was fantastic. 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…. I had it all figured out. We would pool the best material from Mick and Keith, Paul and John, Bob and George, and then select the best rhythm section from the two bands to suit whichever songs we were cutting. Paul and Mick were probably, right, however I would have given anything to have given it a go.
