The theme song for the television show "Friends" is called "I'll Be There for You," and it was performed by the American duo, The Rembrandts. The band consists of Danny Wilde and Phil Solem. The song, which was co-written by the band and the songwriters of the show, became one of their biggest hits and is synonymous with the popular sitcom. It was released as a single in 1995 and reached the top of the Billboard Hot 100 Airplay chart in the United States. It's worth noting that the song was not initially a full song, but due to its soaring popularity after the show's debut, a full radio version was subsequently created. So for any "Friends" fan or someone who is interested in TV soundtracks, "I'll Be There for You" by The Rembrandts is essentially a good piece of trivia to know.
