It's a precursor to Euston films as it was shot by Thames on 16mm in colour but only shown in black and white. There's a few extracts from Pink Floyd's Saucerful Of Secrets but definitely more psychedelic than prog. We get a few bursts of The Stones, The Nice, Cream and The Moody Blues plus more early Floyd. The scenes shot in London in a warm summer of 1968 are great. Philip Madoc is the most famous name in the drama where 3 youngsters are trying to find 'The Tyrant King'. I've seen four episodes so far and am enjoying it's unsettling feel.
