Ok, so i'm having a crack at logic, express, and i was wondering if anyone could lend me their expereince in removing the centre channel, ie what is common to both left and right. I've tried inverting one channel and mixing it with the other, to no avail.

Basically i need to a) remove the vocal lines from a song wherein, the drums lie in the right, and the guitar in the left...

and then B) remove said drums and guitars leaving vocals...

I know i could do this in about 20 seconds using sound forge, man that s/w kicks ass... but i don't have a pc handy at the moment. and i can't find a good wave editor for mac. at all cheap or free or expensive!!!
