People come into our lives for a reason. Sometimes it leaves us with joy, other times with sorrow. "Once" proves it's what we do with those chance encounters that truly defines who we are. He was a singer about to give up his dream. She was a patron entranced by his music. Guy and Girl, as they're known throughout the show, begin their relationship when he tells her of his day job as a vacuum cleaner repairman at his father's shop. When she asks him to fix her Hoover, she says she can only pay for the repair with a song. That song is all it takes for Guy and Girl to fall in love, but with that love also comes some baggage. Based on the Oscar-winning movie, "Once" is an eight-time Tony Award-winning musical that's now coming to Aurora's Paramount Theatre.
