Well, bless his heart for seeing his health as a priority... sure its a shame for many fans that still wanting to see him live, but he has to do whats best for his overall wellbeing and health.
I am sure he will more than likely still record...which I am hoping he still does "if" his health allows it.
Otherwise...I wish him all the best.

P.S.
Who is willing to bet that the Dead Daises will now decide to attempt to recall Corabi? LOL.
