Chris Freeman (Australian musician): Christopher James "Chris" Freeman (c. 1950–1992) was an Australian multi-instrumentalist and teacher who specialised in six-string and 12-string guitar for classical and flamenco music.  At the age of 17 he severed the fingertip of his left hand middle finger in a car accident.  It was replaced by a silver cap, which gave him the nickname "Silver Finger".  He released three solo albums, "Thesilger" (1976), "Shifting Sands... Night & Day" (1978) and "Best of Chris Freeman" (1991).  He also issued four albums with keyboardist John Shaw, "Chris Freeman and John Shaw" (1981), "Synthesized Orchestration" (1983), "Synthesized Orchestration Vol.  2" (1984) and "The Best of Chris Freeman and John Shaw" (1990).  Freeman died in 1992 after an asthma attack, aged 41 or 42.
