I, too didn't know anything until I saw Star (I think) or someone in the shoutbox mention he was in the hospital. I had his number because he was going to visit Massachusetts this summer, and we were to hang out.
I sent him an initial message, and he has been texting me back and forth, with the occasional picture like this.
He is still in the hospital, the above message he sent on 6/17 at 3am his time, 7am mine. He is currently heavily medicated which makes texting and getting details difficult. He told me basically he went in because his stomach hurt, and it went straight downhill from there. 12 days later and he is still hospitalized. He is not doing particularly well, but his spirits are up. Clearly you can't keep a good mustache down.
I'm trying to get a hold of his wife, so I can speak to someone more lucid on the scene.
Musties may be called to action in the future, depending on the circumstances. I'll let you all know when and if that's needed. As I say, thoughts, well-wishes, prayers, good mojo and vibrations are all we can do for now.
