I assume he is recovering or has recovered completely, but you just never know. He fell out of the news after Sep. 11, but that doesn’t mean he is irrelevent…
Somebody was just in here asking that. 
Is it the anniversary or what?

No, actually he’s not “okay”, in the sense of “being up and around and nagging his mom to let him go see Bad Company”.
