Debbie Reynolds was 24 years old and pregnant with daughter Carrie Fisher during filming.
The title song "Tammy" became a number one smash hit for Debbie Reynolds in 1957 winning her a Gold Record.
Debbie Reynolds' single "Tammy" spent 23 weeks on the "Top 40" charts, starting 07/22/57. It was #1 for five weeks. It was also nominated for a "Best Song" Academy Award for 1957 (but lost to 'All the Way' from the film The Joker Is Wild (1957).)
Included among the American Film Institute's 2000 list of the 500 movies nominated for the Top 100 Funniest American Movies.
As Debbie Reynolds' biggest (and arguably only) jukebox hit record, this film's theme song became part of Reynolds' repertoire, which she performed in almost every one of her live concert appearances for the next 56 years.
