One of the two arrestees in this episode (Fast Eddie Jennings) is a street musician played by Bill Dillard. God knows where Danny Arnold found him, but Dillard was an actual trumpet player who hadn't had a TV or movie credit since a 1969 TV movie when he got this role. His solo to close the episode, played from inside "the cage," makes a fitting coda to the sixth season and to what was probably Barney's last chance to make deputy inspector.
The pathos of the scene as everyone listens to Dillard playing is broken up hilariously when J. J. Barry as Fred Bauer pipes up and says "What year is this?"
