I really don't know CMM...but those glasses look like the ones he used to fool with around the pop era...like the big frames...they did a concert in tibet and he had on glasses similar to that but all one color...
He looks REALLY skinny...almost unhealthy...maybe (and this is just a guess) but it might have been when he stopped drinking, because alcohol is a lot of empty calories and if he just went cold turkey like he did he was bound to lose a lot of weight. I mean most drinks are about 500 calories a piece...if he was as heavy a drinker as the stories have said then he could have possibly been consuming 3 or 4 thousand calories a day...
3500 calories = 1lb.
So if you think about it...he probably did lose a lot of weight when he stopped...
Just my .02
