Man, that was like guitar porn! I'm a little woozy now. But thanks, dotthewatusi. I didn't realise Johnny has a '59 Les Paul - those are worth tens of thousands of dollars these days. It would be indelicate to wonder how a then-young guitarist in an indie band could afford all these vintage instruments, as well as a rare Pete Townshend original no less, so I shan't mention it.
This bit was interesting too (no wonder it's bloody hard to figure out what he's playing!): "This is a 1962 Epiphone Coronet. Shortly after I got it I put it in 'Nashville Tuning', which means putting on an electric 12 string set (the bottom four strings are an octave higher than standard). It feels like your playing backwards because the higher strings are at the bottom. I used it to double a lot of the Rickenbacker arpeggios on Smiths records, most notably on 'William It Was Really Nothing', it's also the main guitar on 'Half A Person'."
