For me,music is an aural thing,not visual.I can see where you’re coming from re disabilities etc.When I first saw Brian Wilson (ex Beach Boys) after his stroke,I kinda felt the same.But then I closed my eyes and just listened.Yes,his voice was affected just a tad but the magic was still there in his songs.
“Video Killed The Radio Star”……you betcha.Too many people listen to music with their eyes instead of their ears;) .

I understand that, but in Greens case, the mumbling, the basic chords while others filled in didn’t make me want to shut my eyes because I remembered the days in the Nottingham Boat Club with the rubber penis on the amps and the general mayhem of it all didn’t relate to what I was seeing and hearing.
As for Brian Wilson, it was the same thing, yes, try and get away from the bizarre hand waving, but the voice was so naff, c’mon, sometimes we should just remember the legend, sympathy doesn’t always work, from what I’ve seen of Zeps performance from various sources, they can still do it, along with Pink Floyd, they must all be in the Keith Richards mould of surviveability.
I’ve seen the Stones in their dotage as well as their heyday, it’s a bit strange to see them now, Bills lack of presence is a real handicap, but how long will this go on before it gets rather sad.
Thats why I worry about a Kinks reunion, will the band throw themselves into ‘Autumn Almanac’ or have to do Rays, admittedly good, recent songs.
I watched the performance of Paul Macartney over Xmas on his US tour, yeh, right, most of the stuff featured was Beatles stuff, great, thats what the audience wanted to hear, and I loved to hear it myself, but I could see the spectres of John and George lurking behind him, it’s not the same, buy an exotic Island and move in with Kylie and forget it Paul.
