Andy Hallett is from the tiny Cape Cod village of Osterville, part of the town of Barnstable. He attended Barnstable High School and then Assumption College in Worcester. Always shy, he didn’t begin singing until Patti LaBelle invited him onstage at a concert. After moving to Los Angeles he worked as a runner for an agency and then as a property manager and personal assistant. When Buffy the Vampire Slayer (1997) creator Joss Whedon saw Hallett singing in a Universal City blues revue, Whedon conceived the character of The Host, an anagogic demon who reads people when they open up through singing karaoke. Hallett was invited to try out and got the part, his first job ever as an actor.
