We were asked to develop a song that incorporates the personalities of all of the characters: Apple, Herb, Olive and Chip. So, we set out to create a piece of music that celebrates the diverse personalities of the subway kids characters. We did so by coming up with a "sing-a-long" chorus, and then giving each character a verse to explore the different characters. They had not been given voices yet, so with only drawing to work with we were free to imagine what the voices might sound like. We hired out a team for the voiceovers, and recorded this song start to finish.
