'Bruce' came from the Monty Python sketch re the University of Wollomollo. As such it could have been me, Jimbo or even Neil Miller that named you.
Why yes - it certainly could have come from me! I had "Matching Tie & Handkerchief" and "Live at Drury Lane" - lps which featured subtly different versions of the Bruces sketch, genuine black stuff, back in the days when I was a mere callow youth.
