Played on the '60s channel today: Richard Chamberlain's Blue Guitar. It was written by Burt Bacharach and Hal David and reached #12 on the adult contemporary chart and #42 on the Hot 100 in November 1963. The B-side was also a Bacharach-David composition, a nice little ballad called Close To You. Yes, Chamberlain was the first to record it – and after you hear the first ten seconds of it, you'll know why it was not the A-side.
