Let other musicians measure their success with applause and awards. Burt Bacharach's been there and done that.

The writer of 48 Top 10 hits and winner of seven Grammys now knows there's another way to judge the impact of his work. For the first time in his six-decade career, he's getting hissed and heckled. And he's loving it.
