I heard this jazz rendition of James Brown's "I Feel Good" on the radio the other day with a piano playing the vocal part. It was pretty cool, and made me want to learn the vocal part on bass. I tried it, but I'm absolutley lost. I can figure out bass parts alright, and in fact I already did for that song.... but I have no idea what to do with something as complex as lyrics. I don't know what the jazz version I heard was, or I would have tried to learn it from the piano.
