I always thought they were told to leave.

IMO, KISS was never the same after they did leave. They were my Brother's first concert, here in Jacksonville, around November 1976. LOLOL His stub has $7 on it!!! Not $700 or $70...........$7!!!! And he was only 20 feet from the stage. I always wish I had been my Brother's age, concert wise. He was 6 years older...A teen of the mid / late 70s. In other words...BEFORE cocerts were run by CASH GRABBING @#$%&!
