5. 'Holy Joe'
When U2 announced their ill-fated PopMart tour at the lingerie department of a Kmart in downtown New York, they could have serenaded the press with any song from their vast catalog, but for some reason they opted for "Holy Joe," the B-side of "Discothèque." Pop is nowhere near as bad as the legend suggests, and it would have been even better had they included "Holy Joe" instead of "Miami" or "The Playboy Mansion." They haven't played even a note of "Holy Joe" in concert since that press conference.
