Thanks,
The majority of that song was written by my drummer who has the weirdest sense of rythm you'll find. That song was built from drum parts up. He'll write a drum part and a basic melody to go with it which will usually evolve into the bassline and I'll add weird guitar parts, write words and vocal parts and we'll arrange the thing and add changes at rehersal.
He is one of the few drummers I have known that I would describe as "talented" because of his music writing ability.
