Chas, you made me more aware that my knowledge of jazz history has some serious holes! I was aware of Alice Coltrane but didn't didn't know much about her, and I believe I had her name confused with one of John Coltrane's off spring. Anyways, I did a bit of research too, and I still don't know who "Alice" is referring to in "Blues for Alice", but now thanks to you I know a little bit more about Alice Coltrane.
Sorry Gleen, we're getting side tracked! I do love blues vocals, hopefully some members will chime in, post some Youtube videos of their favorite blues tunes and singers. This defiantly an area of interest for me.
