First up is Gareth Brown, the former drummer. He's got.. wicked hair. Uh, yeah. And he's black. He was awesome, bobbing his head up and down haha. Anyway, he's now the musical director. He does still drum occasionally (for example, at Stoke when I saw them), but yeah, he's been 'upgraded', so to speak.
Next is Damon Willson, who used to drum for Maria Willson, one of the support acts on Busted's 2003 theatre tour. Maria has released two singles, Chooza Looza and Mr Alibi. Damon used to look cool with his goatee, but then he looked even better with leopard spotted hair ala Benji Madden (Good Charlotte) stylee! Now I think he's just gone back to black.
Anyway, I've found out a bit about Damon. He used to live in Australia, but moved to England to join a band, Vega Stones. I don't know what happened to them, but he's now in a band called TAT, as well as being the session drummer for Busted.
