Great post, Tom!
That '76 show from San Francisco is a gem. Apparently whoever filmed this got audio straight from the FOH board. It's full of great examples of how talented these kids were. I love Tommy Shaw's slide solo in "22 years", and DDY's piano work on Lady is amazing (especially singing while doing it). JY's strat sounds killer...just a super clean sound straight to his amp (maybe with a MXR distortion+ in there?). Great video.
