So I confronted the technician after being told he was the one who'd done it.
I learnt the following things:
-He's in a long term homosexual relationship (heard his phonecall)
-I make him nervous
LOL. I'm gonna stab him in the neck I think.
In other news, I can play all the Klaxons songs on keyboard, apart from Atlantis To INterzone coz I don't have a Yamaha thingy.
