The U.S. State Department has rescinded an invitation for the rock musician Andrew W.K. to travel to Bahrain and perform at a concert sponsored by the U.S. embassy. The musician had claimed on his website he’d been appointed a "cultural ambassador" and was headed to Bahrain to promote "music, freedom and positive party power." But the State Department later changed its mind about sending Andrew W.K., whose musical repertoire includes titles like "Party ‘Til You Puke." Bahrain is a key U.S. ally, home of the Navy’s Fifth Fleet, but it has received criticism recently for cracking down on protesters and jailing medics who treated demonstrators.
