He's booked to do a Film and Comic Con in London at the end of July, and he's said he's booked to do a film after that in the autumn. He's said progress is slow and that he is hardly getting on his computer at all while he concentrates on rehab.
As Jim says above, he's an entertainer and a great storyteller. He's also a fine actor, and still has lots he wants to do.

He knows he's in the thoughts of many, many of us .. and when he feels he's made significant progress I'm sure he'll post on his FB page .. brimming with thoughts and ideas for the future
