I still buy 45’s and own quite a good sized collection (though most are now relegated to the loft)
My favourite thing about 7", 12" and CD singles are the B-Sides little lost gems not released on LP’s.
So here is a thread of favourite B-Sides I’ll start with one that I don’t actually own on vinyl single anymore. The Jam - Butterfly Collector which is the B-Side of Strange Town.
