The needlessly self-congratulatory air of the party organiser, Mr Chappelle, coupled with his astonishing lack of talent (how bad do you have to be to become a superstar comedian in America nowadays?), makes this a painful bore, as do the relentlessly repetitive, 4/4 rhythm of the rap artists, their atrocious lyrics (many of them mercifully inaudible apart from the usual swear words) and the near-total lack of tunefulness (when Lauryn Hill sings the Roberta Flack oldie Killing Me Softly, I almost wept with gratitude at hearing a melody).
