At least Sullivan let Country Joe and the Fish keep the $2,500 appearance fee. Here's a little bit more about the story, from Country Joe's site: http://www.countryjoe.com/edsullivan.htm

I have to assume that Sullivan was more incensed about the song that the cheer led into ("I-Feel-Like-I'm-Fixin'-To-Die Rag") than about the cheer itself!

BTW, I never was allowed to watch the Ed Sullivan Show. Yes, I said "allowed". I was a kid when the show was on the air, and one of the rules my ultra-fundamentalist parents imposed was "No TV on the Lord's Day (Unless It's Something Special That the Parents Want to Watch, like 'Lawrence Welk')". So not only did I never see Topo Gigio, I never saw Walt Disney's Wonderful World of Color, either. This meant that, at elementary school, I was a social pariah!
