I dont need no doctor (Nick Ashford/Valerie Simpson/Jo Armstead)
First recorded by Ray Charles in 1966. In 2005 guitarist John Scofield recorded the song on an album with all Ray Charles songs featuring John Mayer on guitar and vocals.
I left the beginning in the original key (concert E) so the guitar player can do the special intro as played by John Mayer (notes provided). After the 2nd verse there is room for soloists. A modulation to F brings the song to the last 2 verses.
Here is a version of the Sea Sound Big Band with guest players Bas van Holt (gtr), Ties Voskamp (drs) and Chrisje Catlender (vocals):
