Sometimes you learn something and reject it. Teenagers are infamous for this because they are full of energy with the sense they are on the crest of a new wave and they know everything. Which maybe they do. Still, parents and little brothers and sisters and school teachers offer this and that, and the teenagers barely hear them until some forty years later. A light bulb brightens. Whatever their teachers had pointed out is suddenly relevant. They plug it into their lives somehow and Zap!!! everything is on the right path again.

As a teenager, I shunned the boring music of my parents' era - the crooners, the Big Bands, the Broadway musicals. There were electric guitars, rock and roll, surfer bands, folk music, Motown for us adolescents to explore. There were the Beatles. We were riding the new wave.

But it's some forty years later. Here I am, entranced by Big Band's Glenn Miller and Gene Krupa and Benny Goodman. I look for this and that on Youtube.com. The blasts and synchrony of the trombones, the amazing dance rhythms, the strange wonders of the drummers as they seem to freeze a beat in mid-air. The lyrics of life before we were born - the music of the 1930s to 1950s survives, full of energy, a treasure of fascinating sound and memories.
