A graph of my record collection would trail up from the '40s to have a huge bump for the years I went to high school, and then taper off. But I remember my school library getting "Yes - Fragile". They had a listening station in the library with headphones, where we heard it. Some guy, obviously never having listened through headphones before, put on a set that was turned all the way up. He shouted at the top of his voice "HOLY FUCK, THAT'S LOUD!!" as if to compete with the band in his ears. We laughed, but he disturbed several classrooms down the hall. The teachers came in, found the guilty party, and sentenced him to a bunch of detentions.
