I discovered Hap'nin' the other month when I was looking for soundtrack funk. I loved the track, but it didn't really fit in with the cop/spy tv themes that I wanted. It's from the film Lialeh, an all-black softcore porn flick from 1974. I wouldn't recommend shelling out for the whole soundtrack album as there's some seriously dubious cheese on there, but Hap'nin' is a bit of a gem. There are enough drum breaks in the first 30 seconds to satisfy any groove hunter, and while it might settle down and get comfortable it's still got a bassline that'll scoop your earwax right out.
Sorry, but that's the funk for you.
