The old Terry Wogan tv show . . . . the Cold War Kids have just played their latest single, and then immediately launch into the old Dennis Waterman classic 'I Could Be So Good For' . . . from the side of the stage Bono comes on to share lead vocals with the bum face guy from the Cold War Kids, whilst the tv cameras pan to the side of the stage to show the rest of U2 dancing along to the impromptu cover version . . . Larry Mullen dances like a "groovy rhino".
No, I don't know what it fucking means either.
