Although there are two other actors in the play, this is essentially a one-man short play featuring Thomas Chalmers in an exceptional performance. And, like most of the TV teleplays of the era, it was all done live! Chalmers is an aging salesman--who laments the changes brought with time. As he talks to a younger salesman about it, the young guy says very little--he just lets Chalmers talk. The same happens when an old black porter arrives--Chalmers just talks and talks. It's a great case of very good acting--though there isn't an especially deep story here--just a nice little vignette.
By the way, there is some bad music throughout this piece. There's an odd strumming sound throughout--like cat walking across a banjo. I couldn't see much point to it.
