Maybe twenty years ago I read an interview with engineer Eddie Kramer. I think it was in Guitar Player or Guitar World. He spoke about the first playback of Dancing Days. A story we all know. But in this interview he said that once Dancing Days was played for the first time, the four members began dancing, including a moment where they were dancing in single-file in a conga line, with hands on each others’ shoulders.
One-two left kick, one-two right kick. Repeat as necessary.
I have searched around this site and others and have found reference to that day, but never the conga-line thing
