As an aside, it's well known that Chris was a hedonist and liked a drink.
At an event several years ago, a catering girl who had done a Yes tour told us that Chris' on-stage tipple was a Pint measure (or something akin to it) of brandy and white wine! I can't recall the proportions but another tech and I ordered them at the bar one night. With another, empty glass we experimented with proportions but each time we found the combo undrinkable.
Rock on, Chris, you were some machine.
