My biggest problem debunking claims like this is my memory of those times is patchy, at best. Sieve-like is probably a more accurate adjective. So when these wild tales about long gone shenanigans erupt, my whole defense consists of spluttering "I did no such thing." No one at the table even pretended to believe me.
Speaking of drugginess from days gone by, let us consider this newish, bang up version of Pink Floyd's Shine on You Crazy Diamond. The song manages to hit both the tune's motha-o-gawd-I-am-tripping-like-a-thousand-screaming-monkeys effect and also a nod to the very bluesy sound those incredibly white English bands were shooting for in those days. Pink Floyd, Cream, Traffic, Rolling Stones, everyone wanted to be Blind Willy Lead Foot Pig Meat Johnson.
I like it.
