I have seen the Damned several times.
Once in Inverness with support from the Alarm and also Henry Cluney from Stiff Little Fingers. Henry came on stage with on his own with an electric guitar. For his last two songs, the drummer and bassist from the Damned helped him out.
I see the Damned are back on tour this year with the original members including Rat Scabies.
Back to the original question. Probably Stiff Little Fingers, the Stranglers, the Damned and the Rezilloes.
