The truth about the iconic theme song from Seinfeld

It's been revealed that the theme song from Seinfeld that we all know and love was almost dumped at the last minute.

In a recent interview, the man behind the show's unique sound, composer Jonathan Wolff, admitted network bosses originally hated what he'd come up with.

"Everybody loved the music - Jerry [Seinfeld] loved it, [writer and producer] Larry David loved it, everyone - except the network," he recalled.

"They said 'can we not afford real music? It's distracting, it's annoying'."

But, thanks to David's persistence, "the music stayed in the picture."

Wolff also indulged that the song was improvised for every single episode in the series, which ran from 1989-1998.

"The theme song was different for every episode," he revealed.

"I have no idea how many themes we did for Seinfeld. I knew each monologue was going to be different because [Jerry] tells different jokes, so it had to be adjustable.

"I noticed that Jerry has a lyrical delivery to his jokes, and I put a clock on it ... and that became the tempo for the theme," he said.

"The bassline is so simple it can start and stop for his jokes, hold for laughs, and that way I could architect each piece of music for each monologue, Lego-style."

Despite Seinfeld's phenomenal success, Wolff revealed that the cast and crew weren't optimistic about the show lasting. 

"When Seinfeld first started, none of us expected it to last."
