1978 No.1 Hit, Originally Written for a Movie, Defined a Generation

There's no denying that many classic films owe part of their legacy to unforgettable title tracks. While the 1978 musical romantic comedyGrease defined a generation of fans, its iconic theme song also rose to the top of the charts, becoming a hit in its own right.

John Travolta and Olivia Newton-John starred in the hit film Grease as Danny Zuko and Sandy Olsson during the greaser era of the late '50s. It followed the two teenagers as they re-meet at the start of a new year in high school after falling in love over the summer. Grease went on to become the highest-grossing film of that year and earned an Oscar nomination. Alongside its storyline, the film also became a classic thanks to its soundtrack.

Besides "You're the One that I Want," Grease's title track also dominated the Billboard Hot 100 charts that celebrated the greaser era. Bee Gees' very own Barry Gibb developed the track "Grease, with Frankie Vallias vocals, and it was released as a single for the motion picture.

With Grease having originally been a 1971 on-stage musical, "Grease" was one of the four original songs commissioned for the film that never appeared in the play. It's also one of the only tracks from the original soundtrack not performed by the movie cast.

As the story goes, Gibb had enlisted the help of Peter Frampton to play guitar for the song's development session. Gibbs also served as the main vocals before turning to Valli, who had a similar vocal range. Valli was also chosen due to his popularity as a singer from the pre-British Invasion era, when Grease takes place. When Valli agreed to record the track, he had no recording contract, with the film's title track earning him a deal with Warner Bros.

In an interview with Billboard in 2013, Vallie revealed he was given the option of performing the track or appearing in the film.

"Well, I had already heard the title song, and I loved it. I called [famed arranger] Don Costa up and told him to come over right away and hear this song. He said, 'If you don't record this song, you're crazy,'" he explained.

If he had appeared in Grease, he would have performed "Beauty School Dropout," which was instead performed by Frankie Avalon. Despite that track also becoming popular, "'Grease' was one of the biggest records I ever had in my career."

"Grease" went on to dominate the Billboard Hot 100 charts at No. 1 and landed at No. 13 on the Adult Contemporary charts. Fans can hear the track during the animated opening scene of the film and during its ending. Valli would later release a follow-up album mimicking the lyrics of the track, with "Grease" having been one of his top hits as a solo artist.
