The original line up consisted of Jr. Walker, Willie Woods (bass), Vic Thomas (organ), and Billy Nix (drums). Motown session players' don't play behind Jr. on these tracks like they do on his Motown recordings.
"Brainwasher" the groups' second Harvey single is an upbeat groove driven by Walker's tenor and Thomas' impressive organ, Junior excitedly shouts "wind it up" near the end. Jock's flipped it, however, for the seductive "Cleo's Mood." "Good Rockin'" their third and final Harvey single is aggressive, roadhouse R&B. Motown omitted their Harvey debut "Twist Lackawanna" but stuck it on another album. Soul Session's loaded with tight grooves composed mostly by Walker, with some collaboration with Willie Woods. Vic Thomas contributed "Hewbie Steps Out" and Fuqua provides "Three Four Three," and "Decidedly."
