MANILA, Philippines - Local fans were ecstatic after hearing the hosts of a morning TV program discuss the still ?under negotiation? U2 concert in Manila. Concert promoter MTV Philippines and supposed event sponsor Smart Communications insist there is ?nothing definite.? The rumors persist, though, and the latest is that the most probable date would have to be sometime in November, ?way after the Beijing Olympics,? and that the Big Dome would be ?too small? for the Irish supergroup. The open field at the SM Mall of Asia in Pasay is reportedly being considered.
