But after watching this video, you will.
Glenn Murphy, Oisin O'Callaghan and Ronan Scolard are three Irish gents (as if you couldn't tell from their names) who met a year and a half ago at University College in Dublin. Though they were all involved in different courses of study, they bonded over a shared love of music and started putting together cover versions of popular songs, harmonizing like ruddy little angels.
Interestingly, "I'll Be There For You" was actually co-written by Friends producers David Crane and Marta Kauffman, Michael Skloff (Kauffman's husband), Allee Willis, Phil Sōlem and Danny Wilde (both members of the band who performs the song, The Rembrandts). After writing the tune, they offered it to R.E.M. and They Might Be Giants (the latter of whom would later perform the theme to Malcolm in the Middle).
We bet they never imagined their bouncy, Beatles-esque tune as a beautifully harmonized piano ballad, but we're happy these boys from Ireland did. (And also a little wistfully sad.)
