Moustache of Insanity are...

Nik

Nik plays the keyboard badly and sings...ever so slightly better. He also makes thumping bleepy sounds on his Game Boy. He writes the majority of the lyrics and stuff.

Bill

Bill plays guitar and sings. He also writes lyrics occasionally and makes alot of the backing beats in Fruity Loops. he also plays bass with Allo Darlin' and Darren Hayman & The Secondary Modern. Oh and stuff.
