"Private Hell", by The Jam. Live.
Until I saw this, I had no idea precisely how good a guitarist Paul Weller is. My estimation of him has just gone up maybe tenfold.
I saw The Style Council in Melbourne many years (decades) ago, but I must admit I spent the entire concert focussed on Mick Talbot's electric piano and wondering whether it would actually topple over, given the pounding he was giving it. (Plus, as this actual footage reveals (I love the internet), Weller wasn't playing guitar; he had too many moves to bust.)
Also: note the similarity between the letter "P" on Weller's guitar and the Portishead logo. Coincidence, surely.
Also: I want his glasses.
