Phil Medley, whose big ol' face adorns the back of this album, was a songwriter most famous for "Twist and Shout," as originally performed by the Top Notes (produced by a not-yet-mad-genius Phil Spector!), then made famous by the Isley Brothers, then made famous-er by The Beatles. I should note that Mr. Medley is also the uncle of one Sharon Brown, famous for the 80's hit "I Specialize in Love."
From what I can gather, Happy Walk is the first album released under his own name (with the help of his M.V.B. Orchestra & Chorus) followed by only one other full-length a year later. Not sure what happened to the guy, because his talent for funky breaks and groovy melodies is hard to ignore.
The album is mostly instrumental, with some sparse vocals thrown in here and there, and rides the line between Funk and Jazz masterfully. I would say it feels like Isaac Hayes collaborated with the Rat Pack, and everyone felt good about it. Not many albums will make you want to learn how to waltz and break dance, but this is one of them.
