Once is a musical stage adaptation based on the 2007 film of the same name by John Carney. Like the film, music and lyrics were by Glen Hansard and Markéta Irglová, including the Academy Award-winning "Falling Slowly". The book for the musical was written by Enda Walsh. The musical premiered at the New York Theatre Workshop in 2011, before transferring to Broadway in 2012. The production received eleven 2012 Tony Award nominations, and won eight including Best Musical, Best Actor and Best Book. The musical also won the 2012 Drama Desk Award for Outstanding Musical and the 2013 Grammy Award for Best Musical Theater Album. It has since spawned a London production, with a North American Tour which started on 1 October 2013.
