 When Somerset is in his apartment, he can be heard listening to a  radio broadcast of John McLellan. McLellan was a Boston disc jockey  (among other things) who did live Tuesday night broadcasts from the  Boston club Storyville, on WHDH radio in the early 50s. In the clip  in the movie, you can hear McLellans voice announcing some of the  members of the band at Storyville that night, including Charlie  Parker with Herb Pomeroy on trumpet.
