Yes, they’re not kidding.

As a little bit of trivia the only 10 minutes silence song that I remember as being in my collection is a B side of an ill-fated comeback attempt from Rich Dodson who you may remember from the Stampeders from 1971’s ” Sweet City Woman”… He entitled The Cut “John Lennon remembered”

Upon playing it, I remember deciding to play the whole thing through to see if the whole side was silent. It was.

A different time, I guess.
