Sidney Palmer, portrayed by Jovan Adepo, is inspired by jazz bandleader and businessman Curtis Mosby. According to The Syncopated Times, in the 1920s, Mosby founded his band, the Blue Blowers, which became popular enough to appear in films like "Music Hath Harms" and "Hallelujah" toward the end of the decade. Along with his musical accomplishments, Mosby also owned several nightclubs in California throughout the 1930s, some of which were frequented by well-known musicians, artists, and actors at the time.
