Beyond his vocals, melodies and arrangements, there is a certain sense of the absurd about John as a performer that is reminiscent of the American rock stars of the mid-1950s.

Only someone with that wild, uninhibited view of his music would dare ask the audience to sing along — something that is almost never done anymore — or drop to his knees, like Jerry Lee Lewis used to do, in a rousing piano finale on “Burn Down the Mission.” It worked wonderfully well.
