Jimmy Buffett played a free show at a restaurant owned by his sister in Gulf Shores, Ala., on Wednesday night (June 30). Word about the show at Lulu's, operated by Lucy Buffett, circulated on Facebook and hundreds of fans showed up, according to USA Today. According to the publication, Buffett adjusted one of the lyrics of his signature song, "Margaritaville," to proclaim, "I think it's all BP's fault!" Buffett had originally planned to host a free concert in Gulf Shores on Thursday night (July 1) but postponed it until July 11 due to Hurricane Alex. As previously reported, CMT will air the July 11 concert live and without commercial interruption.
