Hi Pete, yes very rare and it probably didn't make it out of the warehouse officially. It was probably a demo thing that Ashford & SImpson did with Jo, and maybe even Stanley Greenberg. No idea why they put it out, I meant to ask Ed Silvers if he recalled it when I interviewed him, but forgot all about it. Valerie says it ain't her, which leaves Jo A as the likely culprit on the vocal version that Ady C located (I haven't tracked Jo down yet). They obviously just toned down the vocals on The Camp 45, like they did on several other tunes. There were quite a few things they didn't put out on demo, all very hit and miss.
