Although known primarily for his trumpet playing as the leader of the Tijuana Brass, Alpert sang lead vocals on this solo recording, arranged by Bacharach . </P> <P> As documented in a Biography cable episode featuring Bacharach, the recording originated when Alpert asked Bacharach, "Say, Burt, do you happen to have any old compositions lying around that you and Hal never recorded; maybe one I might use?" Alpert said he made it his practice to ask songwriters that particular question; often a lost "pearl" was revealed . As it happened, Bacharach recalled one, found the lyrics and score sheet, and offered it to Alpert: "Here, Herb...you might like this one ." </P>
