Whilst not knocking Gemm - cause it's fucking excellent (as is the UK based Netsounds.com). Don't buy the one from Hard To Find for $17.26 - It's deffo the bootleg ("Premier Tunes Vol1" bootleg to be precise) not the Positive Vinyl release. It will only be the Piano dub mix, not the Can't Stop The Feeling mix. The Positive release is in their "we want" section so you'd be looking at absolute minimum £30 off them.
I wouldn't be too sure about Deephouse's copy for $21.99 either. He's a bit of an ebay regular and well knows his tunes. He's put the record down as USA origin. I could be wrong but I'm fairly sure it never got a US release. If it was the Positive Vinyl release he'd say so on the description.
With fear of me sounding like a mercenary and going against the Old Skool ethos of generosity and all that bollox- I've got a spare copy of the original Positive Vinyl release with both mixes on. I'd sell it for £17 including postage. That may sound like alot but it's a well rare track that I could probably get at least that on ebay.
Send us a private message if you're interested (and if you've not bought one of those off Gemm of course).
