No, I don't have it and I have heard these rumours about it being a spoof and sure, it might be, but I don't think there's any proof in the picture which I posted above that confirms it being a fake. PErhaps it's me who's cynical, but I just thought that this "rumour" was spread by people who wanted to be able to still play it from their LPs and feel "good" about it (you know how it is to play a tune from an LP when a far rarer 7" exists of the same track ). The scan above was posted on either this forum or the RSF forum and the 7" is supposed to belong to Ian Clark. It was photocopied onto a paper and then scanned (that's why there's a line running through the scan, where the paper had been folded).
The other Solid Solution 7" on Silver Spoon (#7117, "L.O.V.E."), which DEFINITELY exists, has also got plain text for the label name.
"Think About It Girl" is supposed to be #7119 if you look closely in the scan above.
That's all I know and I really, really wish that it does exist on a 7" because I want to own one.
