Chapman wrote ““Give Me One Reason’’ in 1986; she sang it in shows, but never bothered to record it. Elektra Records made it a single and sent it to the rootsy Triple-A (Adult Alternative Album) radio stations last September. It took months to hit pop charts, but by last week it had sold 700,000-plus copies, and the album, ““New Beginning,’’ was at No. 5. Whoever dreamed up that title last year should have been out buying lottery tickets.
