Well, Jimmy Smith was a really incredible jazz organist, his CD 'The Sermon' is available on Blue Note records, should be really easy to find. I can send you the transcription, but you need to listen to the cd to see how he grooves, how he plays it, you know?
You do read music right?
The Sermon is great to start off with, it's just a blues in F, and he plays a little more sparsely than his harder hitting stuff, I'm currently learning it in other keys. I don't have the transcriptions scanned into a computer, but I will get that done for ya...it might take me a little while, so be patient
