curiousjim, glad I could get your toes tapping!
stuartk, the reason I mentioned Sinatra was because many musicians and singers have called him a genius. He lost his voice early on in his career, I think when he was in his twenties. Early Sinatra sounds much like Bing Crosby. Sinatra made up for the problems with his voice by inventing new phrasing, and it is this phrasing that other musicians refer to as his genius. I wondered if that phrasing would give him a place in the jazz world along with Billie Holiday and Ella Fitzgerald. Every New Years I am absolutely blown away that New York is still playing Sinatra's "New York, New York." He was born 110 years ago and died 27 years ago and I still hear him everywhere, as I do with Ella Fitzgerald.
I grew up listening to Ella Fitzgerald, Sarah Vaughn, and I don't know who else remembers Louis Prima and Keely Smith. Jazz was all around but I didn't think of it as jazz. It was just the music my parents were playing. And, of course, Sinatra was all around.
