Brian Pern is an ageing rock star and former front-man of ground breaking progressive rock group Thotch. Like many artists of his age, rather than make new music, he spends more time trying to save the planet (including his campaign to teach gorillas how to Skype). Now, the BBC have asked him to front a major new documentary where he presents his guide to The Life Of Rock from prehistoric man to the present day.
