Communards Don’t Leave Me, despite being a great tune, always gives me the shivers - it brings me back to the dreaded School Disco. I hated getting up from whatever dark corner I hid for the night in but for that song, everybody got up, so I had to shake my lanky, gangly, freaky thang. And it really was true, everybody was just looking at me!
My favourite Jimmi Somerville tune is Song for a Friend. He has done some really nice live versions in studio in recent years, very worth checking out on Youtube. Voice still has it.
Also on the subject of the dishco, I remember there was a big revival in 60s Soul/Motown etc around the late 80s, and a couple of those tunes always got played.
