Polly, I had to share this with you considering our little history about our prog rock drummer heroes.
It's from a series called I'm In A Rock 'N Roll Band and this is part 4 of the part about The Drummer. I'd recommend the entire series as it's pretty interesting as rockumentaries go, but this particular clip features a moment that cracked me up. As they're describing the self-destructive lifestyles that led to early ends for Bonham and Moon, they show a typically somber Bill Bruford who somehow manages to use it as a launching pad to chastise the viewing audience in his own special way.
Gave me a chuckle, giving the history of our back-and-forth. The Bruford moment is at about 6:11. Enjoy!
