A classic TV moment. Similar to Elvis Costello, who was supposed to play Less Than Zero, breaking into Radio Radio on the SNL stage.
Elvis Costello actually did return to SNL years later, and interrupted the Beastie Boys in the middle of doing “Sabotage”, and then Elvis and the Beastie Boys together performed “Radio, Radio”
