Jimmy Stewart quotes Shakespeare

The exact quote is from Hamlet: "Goodnight, sweet prince, and flights of angels sing thee to thy rest." We hear Jimmy Stewart as Bret Ponsett in the radio show The Six Shooter very unwillingly quoting  this line in the episode entitled, "The Actors." Two of his friends had asked him to appear on stage with them to keep the locals from being unruly, and he had to quote this line.
