This is the studio version with Tommy Cogbill on bass. I had heard only the Live at Fillmore West version with Jerry Jemmott on bass. There are many similarities, but Jerry's has many more variations and subtleties. I do like Tommy's line in the last measure of each 12 bar pattern (see measures 24, 34, and 44). Thanks to ChrisDev for the transcription of the later live version and suggesting this comparison. King Curtis - Memphis Soul Stew (Live) | Bass Transcription | Jerry Jemmott
