Gumshoe was a latecomer to the Channel 10 group, arriving on the scene when the group was already in decline in the early months of 1976.  He became good friends with Tom (LIM), and they often went out to the "nightclubs" together.  Later in the year, when some of us moved to the Channel 6 group, Gumshoe followed us there as well.  Tom managed to play a practical joke on Gumshoe, in this audio clip.  Gumshoe pretty much faded away from the scene by 1978 and I haven't heard from him since then.
