Actor Joe Penny apparently doesn't play piano, as his hands almost never move from the same keys whenever he's "playing."
Whenever Frost plays the piano his jail clothing changes to the era he plays - yet when Shaughnessy takes over playing and is transported to prison, if the thing works consistently he is still wearing a tuxedo when his clothing should change to prision blues.
Frost: How do you get them to leave you alone?
Eddie: I believe in the eleventh commandment. Do unto others as you would have them do unto you. But do it unto them first.
