Frank Turner - Balthazar, Impresario Lyrics. The lyrics of this song have inspired me in multiple ways. The subject of the song is sang from a musical performer explaining how he is singing his last show. He talks about how his 'craft (music) has been forgotten by the age'. Also, the chorus inspired the title of the film. I felt the lyric 'Once more to the boards' represented Al's career in performance and crafting of guitars.
