Este Muchacho Esta Enamorado De Ti (Yo Soy Ese Amor) = This Guy's In Love With You

This Guy's In Love With You was recorded by Herb Alpert in 1968, marking a significant departure for the bandleader. While Alpert was known primarily as an instrumentalist, he performed this vocal track live during a television special titled The Beat of the Brass. The song’s popularity following the broadcast was so immense that A&M Records was compelled to rush-release it as a single, despite Alpert's initial hesitation to record vocals.

The song was composed by the songwriting team of Burt Bacharach and Hal David, whose sophisticated melodic structures defined much of the era's adult contemporary sound. Alpert’s performance, characterized by a vulnerable, intimate delivery, stood in stark contrast to the brass-heavy, upbeat aesthetic of his Tijuana Brass records. It became the first number-one hit for A&M Records and solidified Alpert's status as a versatile vocalist, effectively broadening his commercial appeal beyond the instrumental easy-listening market.
