The soundtrack album to Barbra Streisand's 1979 boxing comedy film with Ryan O'Neal included different versions of the disco hit “The Main Event/Fight.” Bob Esty, who co-wrote the song, explained how the tune was written: “Paul Jabara is signed to First Artists publishing and when he found out what the movie was to be about, he and Bruce Roberts went ahead and wrote the song hoping they'd consider it. He submitted a demo, but it was rejected and just laid around for two months.
“Barbra had hired Marilyn and Alan Bergman to write a Way We Were
type of ballad for the movie,” Esty explained, “but [Producer & Streisand's boyfriend] Jon Peters thought it should be an uptempo tune since the movie's a comedy. So he talked [Streisand] into reconsidering because he wanted her to do a contemporary thing, a dance tune.”
Streisand, Esty stated, “worked real hard to try to make [the song] work. She's very cooperative.”
Streisand did suggest that the word “fight” be worked into the song. Esty and Jabara had already written a tune called “Fight” for another album. “It was perfect,” Esty said. “We just looked at each other and said, ‘have we got a song for you.’”
Soundtrack album producer Gary Le Mel told Orange Coast Magazine
why different versions of the disco song were included: “We didn't want to cheat the public. We wanted to give them what they heard on the radio,” he explained. “We had made a 12-inch disco version of the song, but it was only for discos and disco radio. It wasn't available for sale*, so we put them both on the album.”
As for the ballad version of “The Main Event,” Le Mel said, “Barbra liked the song so much she wanted to try it as a ballad. I think that's the nicest version on the album.”
Bob Esty conducted the strings and Bruce Roberts played the piano on the ballad version.
