Song:- "Can't help Myself (SugarPie Honeybunch). Key of C. Bassline:- Jamerson Notes in question:- 3rd line "can't help myself":- is it:- D,A,C or D,A,C # ? Played this a million times both ways. Still have issues with it. Maybe I'm doing it totally wrong. Don't know. Yep.Simple. But it's bugging the heck out of me.
