Many of my favorite film scores were composed by John Barry. Barry is best know for his work on the James Bond films. One of his first film scores was for a 50's juvenile delinquent film Beat Girl. That song, featuring the twangy guitar of Vic Flick, was recycled by Fatboy Slim into the 90's hit song "Rockefeller Skank."
He died over the weekend at age 77. Here is the BBC news obit. If you want to check out his music you can find a whole page of downloads at Amazon.com.
