I learned by listening to other people sing and doing impressions of them. And there are things no one can ever teach you, like phrasing. By listening to Sinatra, for instance - you felt that everything he sang had happened in his life.
One day, when I was still living at home, a friend told 'Texas' Jean Valli about me. She was originally from Syracuse, N.Y., and lived in New Jersey but sang country. One night, she had me come up on stage where she was performing. I sang 'My Mother's Eyes,' and she was knocked out.
