Aerosmith guitarist Joe Perry revealed that frontman Steven Tyler didn’t get “This Is Spinal Tap” when he saw it for the first time.

“This Is Spinal Tap” is a 1984 mockumentary and followed the trials and tribulations of the semi-fictional band Spinal Tap.

Joe recommended “The Is Spinal Tap” to Steven, but he didn’t see the funny side of the film when he went with Joe and his wife to see it at the theater.

Joe said, “He was squirming and squirming, and he did not laugh the whole time. It was like he took the band’s side on everything. It was like he didn’t get it. He got indignant. And it was, like, I couldn’t believe it. So, my wife and I were cracking up and we’re watching Steven.”
