Trivia: At the beginning, when Wyatt is "removing" Dujour, he says to the pilot, "Take the Chevy to the levee." I'm fairly certain this is a reference to Don McLean's song "American Pie," written for the death of Buddy Holly, a famous 1950 rock-and-roll singer. One of the lines in the song is, "...took my Chevy to the levee but the levee was dry."
Trivia: During the plane ride, right after Wyatt gives the girls their record deal, Alexander asks his sister "I still don't know why you're here." She answers by saying, "Because I was in the comic book." Josie and the Pussycats was a TV show and a comic book in the early 70s.
Josie McCoy: If I could go back in time and change everything back, I would.
Melody: That's really cool. If I could go back in time, I would want to meet Snoopy.
