Standard celebratory fare made interesting, as ever, by Trey, who toys with tone, meter, and "2001's" signature theme, amidst the song's backdrop beat.

Things get interesting come the six-minute mark, with more by way of full-band improvisation, play offset by groovy Page and marked, come 7:00, by truly unique Trey, his strange (cool) sort of slow-as-melting-snow descending pattern (kind of like "Twinkle Twinkle Little Star") inciting more synth-driven jamming.
