I acquired my Penthouse and Pavement LP by swapping it for a Nine Below Zero LP (we used to do a lot of barter - I remember swapping a pair of burgundy shoes for a bottle of Drambuie and a fiver). I made the trade, which I thought was quite a good one - I was selling a sinking band for a rising one - as I was on the turn from being a mod to being something else. I'm not sure this something else had a name, other than the catch-all New Romantic. I bought a zoot(-ish) suit from Oxfam, some burgundy shoes (those ones), grew my hair, learnt that swinging arm dance and the job was done.
Being a mod involved a lot of hassle - being chased by grebos and skinheads who all seemed to be bigger, hairier and uglier than we 'little mods'. Also following something a bit artier seemed a good move as that's what the older girls were into.
Before being a mod I'd been a rude boy, which like being a New Romantic also didn't seem to provoke people as much. It's perhaps no coincidence that both ska and electronica have worn very well. But mod, not so much. There's something a little bit irritating even about The Jam.
As for the some of the other groups, well judge for yourself. Here's 'My World' by Secret Affair. I still get a thrill hearing it but that may just be an echo of the adrenalin rush I got from being chased through the market place by leather-clad greasers.
