I'll buy your theory, Jerry. Our US history is full of parallels where one ethnic group's musical style merges with another. Doesn't our stage musical tradition comes from a blending of German orchestral music and Anglo-Irish lyricism? And Gershwin wouldn't have happened without his Russian musical roots slamming into New York blues and Tin Pan Alley at an early age. Something unique was the result.

Compared to other pop and rock music, you can see in doo-wop where 'bel canto' singing, falsetto, and over-the-top sentimentalism are very much featured, yet overlayered on the American quartet traditions (bbshop and gospel both).

And jimmyt, Johnny Maestro is indeed Da Man!
