I remember that one well. Of course the whole fun is watching loyal listeners go apoplectic over it - their lives are just DEVASTATED by what is going on!Don't remember what year but KROQ and KQLZ Pirate Radio flipped their formats.
Pirate Radio was playing Duran Duran and Culture Club and The Cure while KROQ was playing Motley Crue and Poison and Cinderella.
Sluggo was taking calls on KROQ with his listeners going apoplectic about the stunt.
Remember, they have taken all of the FUN out of radio for a long time now, so stunts like this are no longer allowed ("we might miss a PPM reading!")
