Unique theme song

The 'Seinfeld' theme song is nearly as iconic as the show itself, but no two versions are alike!

In fact, composer Jonathan Wolff revealed that the theme song had to be different each time because Jerry Seinfeld was always telling new jokes.

He said: "I have no idea how many themes we did for 'Seinfeld'. I knew that each monologue was gonna be different because [Jerry] tells different jokes. The timing, the length — it had to be adjustable. Each monologue had its own recording of the 'Seinfeld' theme to match those timings."
