Driven me crazy hoping to identify and reconnect with this truly great American (30-40s, black and white) movie:  Keystrokes — A prominent, kindly and popular businessman in a small town is mugged by the train tracks on his way home from work, wakes an amnesiac in a bum’s clothes; believing he is a bum (or hobo), leaves and returns many years later — still amnesiac — He is covered with snow sleeping on a park bench when is rousted by a policeman, then is invited a stranger into a generous and proper family’s home for Christmas by a young man and is last seen entering the home  — fade to end movie. Guess who’s home and family it must be?  But it quits just before what would have been a fabulous reunion… Help – and if found, enjoy. JBF
