This is superb music making. Because each year's Festival had its own "look": decisions made at the production level, these differences do figure in the overall visual impact of the film, especially when viewed with the "play all tracks" option. Most of the better looking are the naturally lit: open air shots where the performance takes over from the effects...the music reigns. Punchy stereo mix. Solid guitar rock. Watch this. Play it loud!
[Pity they had to give Paul McCartney pride of place as the finale, the highpoint of the video. While good, his is not the strongest performance.]
