Punk to me was;
The Clash
Stiff little fingers
Buzzcocks
Sham 69
Vice Squad
Ian Dury & the blockheads
Joy Division
Siouxsie & the banshees
The Ruts

I do remember The Exploited's (Dead cities) first and last time on Top of the Pops ~lol~ my Dad nearly had a nervous breakdown

Edit: He watched it with us - for Pan's People
