First released by Tiny Topsy (1959).
Hit versions by Roscoe Gordon (US #64/R&B #2 1959), Roy Head (US #39 1965).
From the wiki: “‘Just a Little Bit’ was developed when Rosco Gordon was touring with West Coast blues artist Jimmy McCracklin. According to Gordon, McCracklin started to write the song and agreed that Gordon could finish it with both of them sharing the credit. Gordon later presented a demo version to Ralph Bass at King Records, who was reportedly uninterested in the song. Gordon then approached Calvin Carter at Vee-Jay Records, who agreed to record it.
