Thanks again. Currently I'm just using my electric kit, playing along to the songs through headphones with a mix of all three parts. I think it's definitely good advice to be 100% with your limbs before stick stuff over the top. I have a practice tomorrow night, if it's so far from being anywhere near good, I'll just get someone else in the band to learn it the rhythms that are too difficult. Or be a manager and get a drummer who can sing and play. For some tracks that I've not even touched the kit with, I tried to write it all down in a linear format so i could see where the beat of each part related to one another, effectively treating my voice as another limb. Think in my head the theory worked for some bits, though I reckon it needs refining. There is a few harmonies in the KOL song, the second which is a sustained note, though its that 3/2 cross rhythm the first hook employs. In theory should sync up with the drums, though the beats land within 16th of each other. I'm pretty sure the drummer in KOL sing that part as well. Bastard.
