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. She was 72. Animator and producer Prudence Fenton, who is described by a family friend as Willis' "partner and soulmate", is reportedly "in total shock" after the sudden death of her best friend, which occurred just after 6 pm, reports variety.com.

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" and "Boogie Wonderland", and "You're the best", which is the theme track of "The Karate Kid".
