Songwriter Allee Willis, who is best known for composing the theme song of the popular sitcom, Friends, passed away on Tuesday after a cardiac arrest at the age of 72.

Willis entered the Songwriters Hall of Fame in 2018 for a catalog that also included hits such as Neutron dance, What have I done to deserve this?, Lead me on, Boogie Wonderland, and You're the best, which is the theme track of The Karate Kid.

The songwriter was a two-time Grammy winner and was also nominated for a Tony and an Emmy.

Willis had originally written the Friends theme song, I'll be there for you on assignment as a 60-second piece. When the pop duo Rembrandts came on board, they wanted to expand it into a complete song, so contributed a bridge and a lyric for the second verse. Thus was born the full-length version of the song.

Willis recorded her lone album, Childstar, in the seventies. This helped introduce her as a songwriter to other singers of the era. She was also a visual and social artist, painter, director, collector of odd artifacts and memorabilia, and a stand-up comedian and performance artist.

Willis is survived by her brother Kent Willis, sister Marlin Frost and niece Mandy Becker.
