P.S. I Love You (1953)
Words by Johnny Mercer and Music by Gordon Jenkins

Originally the Hilltoppers were a trio formed at Western Kentucky State College (now Western Kentucky University), Bowling Green, Kentucky.
P.S. I Love You did not become a huge hit until nearly twenty years later when it was revived by the The Hilltoppers. Although it is categorized as "Traditional pop" it was actually an early form of Doo Wop, a term coined in 1951 (also the year disk jockey Alan Freed began using the term "Rock and Roll" in his radio show). It soared to #4 on Billboard and #5 on Cash Box on September 5, 1953. Many 1950's American teenage and very young adult couples chose this Hilltoppers' ballad as "our song"...

In 1952 they recorded a song, "Trying," written by Vaughn. A local disc jockey sent a copy to Randy Wood, who was starting a new record label, Dot, and he agreed to distribute the record. It became a Top 10 hit single. They went on to record a number of additional hits until their break-up. Their 1953 release, "P.S. I Love You," sold over one million copies, and was awarded a gold disc.
