Stuart, you superficial bastard.

So, while I agree that the new wave / punk stuff may not align well with uni-concept views of the seventies as the disco era (gotta love the way time via memory plus art turns everything into mush), or the eighties as techno crap, I think it is far more emblazoned on my skull and heart than any of those Hollywood meets Dick Clark versions of those times. It just floats above it, and stands time far better. Remain at least somewhat mush-free if you will.

My choices of shouldabeens would be in a similar vein to Derek's, with perhaps a little more pop in my punk / new-wave mix:

I would start without about half of Derek's bands (esp. Gang of Four, Undertones, T/Heads yadda....) then add

The Records - Starry Eyes
Joe Jackson - Sunday Papers
Dave Edmunds - Girls Talk
Graham Parker and the Runour - Local Girls
Devo - Mongoloid (oh right, Derek had this one)
Brahm Tchaikovsky - Girl of My Dreams
Fabulous Poodles - Mirror Stars
Boomtown Rats - Someone's Looking at You
Television - See No Evil
The Damned - Neat Neat Neat

there are others.
