Junior Walker and the All Stars was always on the periphery of my listening experience, back in the day. I was familiar with their biggest hits, "Shotgun," "Road Runner," "Come See About Me," and "How Sweet it is (to be Loved by You)," but beyond that, not too into them.
Stumbled on the when it came up on Jango (the not-so-great alternative to Pandora):
Junior Walker and the All Stars, "Cleo's Mood/Cleo's Back." Good stuff.
