The media circus: A.J. Mazzetti was gigging most recently as drummer for Flock of Seagulls. He also worked at Wings of Steel, and at his own shop in Hallandale, as a welder. According to friends of his I spoke to, he was working in his shop on June 2 when a spark caught a gas container that then spilled onto Mazzetti (everyone calls him A.J.). He's in Hollywood Memorial Hospital recovering from the first skin graft. The first benefit is at Le Loft on Saturday. Doors open at 10:00 p.m., with two dollar drinks and a complimentary buffet. All door proceeds (probably five dollars, but give what you can) go to a fund set up on A.J.'s behalf.
