God, I loved The Undertones. Hitting the airwaves in the late 70s and hitting their stride in 1980, The Undertones were everything I though Punk music should be about. They were raw, bold, brash, not pretty, taking the best of the 60s rock bands and bringing a drive and beat matched with testosterone. The put out four albums before giving up the ghost in 1983.
Here is another 'live' performance on British television of Here Comes The Summer.
