I was at the 'Baffalo' show. It was outstanding. They reached back a little deeper into the catalog for some songs. A very different show than they played earlier in the tour in Toronto. Maybe because Toronto was a large arena, and Buffalo was a small (2,800 seat) theatre.
I have the Baffalo bootleg, along with an audience shot DVD (jumpy camera, but good sound) of the Toronto show on that tour.
I also have an oddity. A video of the dress rehearsal (shot in Vancouver) for the Thin White Duke Tour. It escapes me now, but I think it's 1975 or 76...lot's of Station-to-Station and earlier songs. Just Bowie, band and some roadies.
