I contribute over at drumforum.org frequently.  One of the guys on there posted this recently:

"Back in high school 1967 - 1968 I cut a record. Many teenage bands made records that go nowhere and they forgot about them. Just for the hell of it I looked up the record on Google: Hurry On Back To Me / Up On the Roof by the Casino Royales. I discovered it is being sold (and has been played in clubs) in the UK and Germany, for up to $175.00 US dollars for a mint copy. This is pretty cool but I guess there are no royalties after 40+ years. I think it's a mediocre record at best but maybe in Europe it's considered a classic of Northern Soul. Pretty funny for a group of teenage white guys. We never played the Apollo that's for sure."

Anyone ever heard of them? 

Yeah, most "Northern Soul" is mediocre, IMHO.

Check out this snoozer:

Not sure if it's the same band you're talking about, though...
