Andy I got one from a boot sale in Hastings once, I'd missed it but this guy rang me up at the dinner time and said I think I've got something for you, a mint Tony Middleton Polydor demo, he said it was an old lady who had it, she only had ONE record, and it was leaning against the tyre of her car and nobody had bothered looking at it except him, paid her 10p for it, I gave him £150 for it, sold it for £250 about 3 days later, that was back in about 2000. Not had one since (a demo that is)
