"This Guy's in Love with You" is a hit song written by Burt Bacharach and Hal David and released by Herb Alpert in May, 1968. Although known primarily for his trumpet playing as the leader of the Tijuana Brass, Alpert sang lead vocals on this solo recording, which was arranged by Bacharach. An earlier recording of the song by British singer Danny Williams with different lyrics, titled "That Guy's in Love", appeared on Williams' 1968 self-titled album.
