You're welcome, Martin :-)
Yes, I was struck by the end of the first part too, I think particularly the trumpet
cha-cha-cha-
cha-cha-cha, if memory serves. The video isn't loading at the moment; I'll try again later so I can listen out for the fanfare you mention. Bernstein seems pretty awesome so I can well imagine him capable of conducting from memory!
I haven't got around to writing the Rite yet, but I'll try soon
Best wishes,
