Covering Marvin & Tammi is a dicey proposition; Ree-Ree sorta pulls it off but this is one of her lesser moments, IMHO.
However, Jackie Moore's "Precious Precious" is a lost gem; I'd never heard it until I moved to SF -- it was a favorite at the late lamented KDIA. Ms Moore's only Top 40 single; she'd make a semi-comeback at the end of the decade with the dance club fave "This Time Baby" in '79.
Oh lord here's that "DOA" thing by Bloodrock. This single is an edit of a much longer LP cut, BTW. And even this version seems endless. What Top 40 station in '71 would've played this? Yikes.
Amusing to hear Casey pondering the new-to-Americans-yet-a-UK-chart-veteran, Cat Stevens.
