Drummond is a genius but definitely a master in the dark arts. I believe he is one of the few to be able to prove his appearance in the crowd at the Sex Pistols gig in Manchester too. I'm undecided if he actually likes music or whether it's a useful vehicle for him to weave his magic.
Yes. Cobalt and Zodiac still do one-off gigs around London. They did one a few years back and Adam Ant turned up completely unannounced in the audience. As they started Prime Mover he got up on stage and joined in. Fair play, he knew all the words too. Bearing in mind this was around the time...
My mate works in IT in London and has a colleague called Geoff. They provide level 3 IT support. By night bald, overweight Geoff becomes Cobalt Stargazer, one half of legendary 80s rockers Zodiac Mindwarp and the Love Reaction.
