I'm no expert on the history of these, but at least some of these cues can be found on this LP, "The Eclectic Ensemble" (Omnisound, MLP 1002):

The image below is the only one I've found of this release. I don't think it was widely distributed, or more images would likely have shown up by now. I unfortunately have no idea what material is on MLP 1001, or if there are more releases on this label.
