Band mates say Gary Moore, guitarist with influential Irish rock band Thin Lizzy, has died. He was 58.  Drummer Brian Downey said Moore's death was a "total shock."  Born in Belfast, Northern Ireland, Moore was a member of Dublin band Skid Row before joining Thin Lizzy in 1973. He left after four months but rejoined four years later and played on the band's "Black Rose" album.  He later had a successful solo career, and his accomplished, bluesy playing won plaudits from other musicians.
