I remember years ago leaving some unwanted records in one of my garages. They'd all gone hellish mouldy, I didn't want them but before I binned them I had a look through them and found a couple of Mirwoods ...
So I thought oh, I'll soak these in some nice warm soapy water they'll be good as new. When I removed them all was well until I dabbed them off with a towel, instantly all the writing came off both labels! I didn't really mind cause back then nobody wanted records even at 50p each. So I just wrote the titles back in with a Bic and threw them into a box with my other records that I planned to keep, I threw the rest away (loads of Punk originals and coloured vinyls, Sparks with the topless girl picture cover, Blue vinyl I think,, The Dickies on Banana Yellow vinyl, Plasmatics on Blood spattered vinyl). A few years later this box of Northern soul OV was propping up a stationary engine that had a wheel missing when I happened to find a wheel during a hunt in a scrapyard.
I took the box away and played some, well I'd only written the titles wrong on the Mirwoods…
I tell people now they are very rare test pressings, invariably they say 'Oooh...'
I also once gave away (to a stunning Gothic girl) a copy of 'Anarchy in the UK' on EMI because it was wrongly credited on the 'I wanna be me' side to producer Chris Thomas, being as I had two other copies from 76 correctly accredited. Collectors will know that Dave Goodman produced 'I wanna be me' and will also know that giving away the mis-credited one was a terrible mistake, that's a whole other story, albeit with a happyish ending.
