I saw this a few weeks ago... Enjoyable enough and all very nice and nostalgic, but there was nothing that hadn't been shown in plenty of BBC4 music docs - it's all well-known history of all the mainstream British pub rock bands.
It would be nice if they explored some more recent music, or more obscure music, or some jazz! Frinstance, I've never seen any docs on the Liverpool scene from 1977 on. Or the goth scene, or UK jazz funk... There's been nowt (that I've seen, at least!) on any sort of improvised jazz, or Industrial, or even on the dance scene in the late 80s on. So rather than yet another documentary on the Stones, Faces etc let's see something on Throbbing Gristle, Mutoid Waste Company and the Ozrics!
Or even what The Kids are doing nowadays - or perhaps BBC4 think they're all hunched over their phones sexting each other?
