Title: Once (musical)
Content:  Once is a musical 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.

A minimalist set is used, including a bar in center stage with chairs lining stage left and right. Exiting cast members simply step to the side of the stage and sit down. They serve as the orchestra from these chairs. The bar is used before the show and at intermission as a working bar for theater patrons.

Title: Once (film)
Content:  The two leads, Hansard and Irglová, are both professional musicians. Director Carney, former bassist for Hansard's band The Frames, had asked his long-time friend to share busker anecdotes and compose songs for the film, but had intended the male lead to be played by actor Cillian Murphy, who was an almost-signed rock musician before turning to acting. Murphy was also going to be one of the film's producers. But Murphy declined the prospect of acting opposite non-actor Irglová (then 17 years old) and also felt that he hadn't the vocal capabilities to belt out Hansard's octave-leaping songs, so he pulled out, as did the film's other producers along with their financial resources.

Title: Once (Pearl Jam song)
Content:  "Once" features lyrics written by vocalist Eddie Vedder and music written by guitarist Stone Gossard. The song originated as an instrumental demo titled "Agyptian Crave" that was written by Gossard in 1990. The instrumental was one of five songs compiled onto a tape called Stone Gossard Demos '91 that was circulated in the hopes of finding a singer and drummer for the group. The tape made its way into the hands of Vedder, who was working as a gas station attendant in San Diego, California at the time. He listened to the tape shortly before going surfing, where lyrics came to him. Vedder recorded vocals for three of the songs on the demo tape, one of which was "Once", and mailed the tape back to Seattle. Upon hearing the tape, the band invited Vedder to come to Seattle and he was asked to join the band.
