Frank apparently drank scotch and smoked right up until his death
He drank Jack Daniels and smoked Lucky Strike Cigarettes up until his death, he was even buried with a bottle of Jack Daniels in his coffin and a pack of the cigs.
In reply to:
I'm sure his lifestyle would have had an adverse affect on his vocal range.
For sure it did but nobody cared, he was Frank Sinatra and sounded great just grumbling almost, Sinatra had that certain special style like Bowie has, some do, some don't.
