"Strangers in the Night" reached number-one on the Billboard charts for Frank Sinatra, and the Elvis Presley version of "Spanish Eyes" had sales of over three million copies.

[6] Singleton went on to write songs for a number of notable artists, including Pat Boone, Nat King Cole, Ella Fitzgerald, B.

[7] "Strangers in the Night" began as an instrumental called "Beddy Bye", by German bandleader and composer Bert Kaempfert, which appeared on the soundtrack of the film A Man Could Get Killed.

[8] Sinatra initially called the song "a piece of shit" after the first take had to be discarded because session guitarist Glen Campbell had made a mistake.

[2] Singleton and Snyder had also reworked another Kaempfert instrumental called "Moon Over Naples" into the song "Spanish Eyes", which was successfully recorded by Elvis Presley, Al Martino, Engelbert Humperdinck, Tom Jones, Willie Nelson, Julio Iglesias, Faith No More, and others.
