SB was the epitome of “mad genius”. Unfortunately, drugs played a destructive role in his case, the greatest problem of all being the time he spent in a “friendly couple”‘ s home : they used to put LSD in his tea every day “to see what happens”, without him knowing at all. He eventually flipped out.
A funny thing has to do with the way he described the other Pink Floyd members, which he had recruited : “a bunch of not very interesting people”.
