Via Galactica is a rock musical with a book by Christopher Gore and Judith Ross, lyrics by Gore, and music by Galt MacDermot. It marked the Broadway debut of actor Mark Baker. Originally entitled Up!, it offers a futuristic story of social outcasts living on an asteroid in the year 2972. Among them is Gabriel Finn, a space sanitation man who collects trash in a clamshell-shaped garbage ship called the Helen of Troy. Via Galactica, one of the first Broadway shows to lose more than $1 million, was MacDermot's second flop of the season. His Dude had closed after 16 performances five weeks earlier.
