. . . all we need is the original disco sample which "they both" sampled ;) - sorry "artistically covered" - brings back my faith which says "I can" be a producer. Reminds me of the game breaks for the beats (or whatever it was called) that Westwood used to play back in the day, only he would play the original sample and you'd have to name the track that sampled the orignal break. Only I wouldn't have a clue of these two - bring on the orignal.
I love sampling me - recycled loops ;)
