yeah all very rare. the my children + two record is the first kool and together 45. I think it's also on the heavy light reissue.
The blackblood is very rare, I traded an expensive funk record to get it from my friend who got a trashed copy from the group.
The soulistics is a known funk record on the a-side, but I love their version of cotton eyed joe, it's so good.
The love foundation I never even heard of until recently. The flip is a killer psychedelic funk thing too.
