Depending on who you talk to, the irrepressible Jools Holland is best known as a blisteringly energetic, piano-pounding performer of boogie-woogie, jazz, and R&B; or as the keyboard-wizard sideman to one of the great new wave pop bands of the '70s and '80s; or as one of the U.K.'s most popular television presenters. And while any one of these accomplishments would be enough for most people, Jools Holland has managed to be all those things in his remarkable show biz career -- a career that's seen him work with almost everybody who's anybody on the U.K. or U.S. music scene from the late '70s onward.
