Yeah.... he does like a smoke now and again.... Clapton as well would pretty much do anything back in the day - it's no coincidence he's got a rehab clinic in Antigua! Zakk Wylde must be about 90% ABV for 90% of the time... Most people have some sort of a poison....

Vai is a great player - and an inspiration of mine, but I find it difficult to take his 'guitar religion' thing seriously...

"shut up and play yer guitar".... sums it up nicely :D
