After seeing me play at an open jam night, a keyboard approached me to do some fusion trio work, which I said I was definitely interested in doing... I haven't played much fusion out, but I don't have any problem with tunes like "Spectrum" or "Red Baron", and after a little work I can handle basic time signature changes ("Proto Cosmos" etc), so I think it would be a good learning and growth opportunity.
Went over to his house, listened to some of his tunes. They're good tunes, I like them. We chat a bit, jam briefly, try some of his tunes out, I say let's go for it. He gives me a couple of his tunes to learn and the names of a couple other songs to listen to and learn for a rehearsal.
One of them is Chick Corea's "Got A Match".
Is it just me, or is this tune waaaaaaaay hard? I can just about make it through the changes at this point, but the head is too quick... I have it up to about 2/3 speed now and I'm not sure how much closer I can get to full tempo.
So please tell me I wasn't being a wuss by telling him I might have to 'shed this one for a few months!

Any tips on tackling this piece appreciated too.
