Once the Musical
Once the Musical is based off of the movie of the same name. I saw the current national tour cast. The main actors were Stuart Ward (Guy) and Dani de Waal (Girl) who had wonderful voices and a beautiful rendition of the songs and characters.
The main songwriters are Marketa Irglova and Glen Hansard who are part of the band "Swell Season" and starred in the original movie the musical is based on. Their song "Falling Slowly" won an academy award.
Once is about a musician (Guy) who meets another songwriter (Girl) and they form a bond. It is set in Ireland with characters of different backgrounds. It won eight Tony awards when it first premiered.
The cast also acts as the orchestra and are extremely versatile.
