For the music, Feldman decided to bring in Burt Bacharach, who had done the score for his previous production "What's New Pussycat?". Bacharach worked over two years writing for "Casino Royale", in the meantime composing the "After the Fox" score and being forced to decline participation in "Luv". Lyricist Hal David contributed with various songs, many of which appeared in just instrumental versions. Herb Alpert & the Tijuana Brass performed some of the songs with Mike Redway singing the lyrics to the title song as the end credits rolled. The title theme was Alpert's second number one on the Easy Listening chart where it spent two weeks at the top in June 1967 and peaked at number 27 on the "Billboard" Hot 100. Alpert would later contribute a trumpet solo to the title song of the "unofficial" 1983 James Bond film "Never Say Never Again" (which was sung by Alpert's wife, Lani Hall).
