KPOO's JJ does a "Lost Soul" feature on Sat nite -- of course, nearly half the songs he plays would qualify, but this feature goes above-and-beyond in the obscurity department. Tonite it was Carol Douglas' "Doctors Orders" follow-up, "A Hurricane is Comin' Tonite". Def the OMGWTF-of-the-week for me.
And hot on its heels: Arthur Prysock's "When Love is New", a late-'76 attempt to go the Lou Rawls disco-comeback route (the song itself is a shameless "You'll Never Find..." ripoff). He actually scored an R&B Top 10 single with it, tho' he didn't fare too well on the Pop side.
And now it's Consumer Rapport's "Ease On Down The Road", that rare regional hit whose region was NYC: it was Top 3 there, without ever making the national Top 40.
