David Foster is a multiple threat: producer, songwriter and author. Best known as the producer of Celine Dion, Whitney Houston, Josh Groban and other pop giants, he published his memoir, "Hitman: Forty Years of Making Music, Topping the Charts and Winning Grammys," last fall. He's endorsing another book, Lee Iacocca's "Where Have All the Leaders Gone?"

So it's full of things like that."
