no TopFlix. Veteran BBC Radio DJ John Peel takes his first visit to Derry and discovers for himself the band that forged his favourite pop song 'Teenage Kicks'.The film, through the use of interviews and archive footage (of Derry and The Undertones), takes us back to 1975. To a time when it would have been normal, even expected, for five Derry teenagers to get together and have a riot. The Undertones got together, formed a band and created their own form of riot, bursting into a vigorous and joyous celibration of their own existence.
