Which song by the Rembrandts is used as Friends’ theme song?

The Rembrandts’ song “I’ll Be There for You” is the theme song of Friends.

The song was written for the television series by the Rembrandts with writers including David Crane, Marta Kauffman, and composers Michael Skloff and Allee Willis. Its instantly recognizable handclaps and upbeat refrain accompany the opening credits, which show the six main actors around a fountain.

The televised version was shortened from the longer recording released commercially. After the show became popular, the song also became a successful radio and chart hit, making it unusual for a television theme to achieve substantial independent recognition.

Some listeners identify the song only by its chorus or mistakenly attribute it to another 1990s pop group. The recording used for Friends is credited to the Rembrandts, and its title is “I’ll Be There for You.”
