When "You Got to Fight for Your Right" came out, the BB's were booked to play on American Bandstand. They were under the impression it would be done like most TV shows, with what's called a "TV Track" or mix-minus version. That is an instrumental mix with no lead vocals. The three of them would sing live over the track, just like most of their TV bookings.
The Bandstand people were not on board. They insisted on "full playback" which is a lip-sync. Beasties were not down with that.
The fights went back and forth all day and various managers and lawyers and such went at it. Bandstand (Dick Clark Productions)was not budging....do playback or not at all.
The Beasties came to a decision.
They went to their green room and duct taped the shower door to seal it shut and put the water on full. Then they took sharpies and wrote on the mirror: "Suck My Dick Clark" and walked out on the taping. It is only one of two or three times in the history of the bandstand that a performance was canceled on show day.

Just a bit of personal rock history from your favorite doorman.
