I can't believe that I haven't heard of this before. Haycock, who played guitar on Hans Zimmer scores like Thelma & Louise, K2, Toys, Calendar Girl, Drop Zone and The Dilemma, died in 2013. He also wrote film music for the films One False Move and Dominator.
I'm also shocked. I loved the Haycock sound, especially on those early Zimmer scores. He was one of the most distinctive guitar players and quite unheralded, too.
