And as a side note, I always thought that if I were stranded on a desert island and I could pick only one singer to listen to, I’d pick Judy Collins. But I’ve recently changed my mind. It would be Frank.

I think Dean Martin had a better voice. But Sinatra cared more about the music. He would pick songs and musicians to work with, and studios and production. Martin just showed up and sang what they gave him.
Dean Martin, Frank Sinatra, Tony Bennett. None of them were perfect.
Not so sure they lived a great life I could deal with it.
