The "Tech Reasons" for the rapid withdrawl of Wearing Thin was 1 an off centre pressing which made it wow horribly (Not nice for an accapella band) and, although it pains me to say it "Red Cross Store" is horribly out of tune...No copyright problems. And as it was on sale for about three hours, You were lucky to have got one allmat!!
Wonder what it would fetch on E Bay? (Sod all I suppose!) but in their prime probably one of the most inspirational UK harmony acts around.
Hope they are all well and happy.
