I listened to a track by punk band The Toy Dolls last night - it was their only UK hit - 'Nellie the Elephant' - reached no.4 in the UK charts in December 1984. This is a track that although it reached a high chart position it NEVER seems to get radio airplay - so it was nice to listen to it and replay the associated memories.
In the UK, the peak of the punk era in my opinion was 1977 - with the Silver Jubliee and the Sex Pistols track 'God Save the Queen' and associated controversy. When the Sex Pistols split up in early 1978, being the iconic UK punk group, within a year or so the UK punk scene slowly came to a halt only to be replaced by New Wave, a few years later Ska and the New Romantics.
Whenever, anyone says punk to me - I associate the movement with the year 1977, after which it all seemed to go downhill.
