1969 King 45: I Made a Mistake Because It’s Only You, Part 1/I Made a Mistake Because It’s Only You, Part 208/07/2011 in Vinyl 45s by jbsuperfan You can get It’s My Thing on this Marva Whitney CD: It’s My Thing. And the vinyl you can get here. Oh my gosh! Nasty freakin’ funk from Marva Whitney with JB and the band. This jam uplifts me every time I hear it, and sounds as fresh as the day it was made.
