Rare 1972 Original. Robben Ford, Guitar, Vocals And Piano; Mark Ford, Harmonica; Patrick Ford, Drums; Stanley Poplin, Bass; Michael Osborn, Rhythm Guitar On One Track. Vinyl Appears Glossy. Recommended. "Middle Brother Robben's Expressive Vocals Defy His 20 Years, And His Bloomfield-Inspired Guitar Playing Is Even More Authoritative. Meanwhile Harmonica-Playing Mark, Only Age 18, Gives Butterfield A Run For His Money." AMG.
