Well done Dave. You are right, good clean titles from this genre are getting hard to find in charity shops. God I've done my share of digging and sifting through thousands of Max Bygraves dished LPs and the like, it can get one down.
Although I've had a few good scores over the years! It's the unknown that keeps one digging.
'Twas far more fruitful pre tinternet days.. in fact Oxfam have vinyl pickers that cherry pick the donations and list the cream on fleabay for the charity. I suppose that's a good thing for the cause but a bummer for the diggers..enjoy!
