Hi guys! Someone will solve this mystery for me right away I am sure. I was in a restaurant today and they were playing some great oldies in the background. I heard a very long [[probably 7 minutes or more) version of A Change is Gonna Come by a soulful female voice but I just could not tell who it was.

It had a long musical intro, to the point that it kept you guessing what song it was going to be. Then at various times there were other musical solos such as a lengthy piano and I think maybe even a string solo. As for the voice, it somewhat resembled Bettye Lavette, but I don't think it was her.

I know this song has been covered a lot but the length of this version might be the thing that helps it stand out. Any ideas as to who it might have been?
