I was breezing through the Internet, caught a brief glimpse of a Monty Python video and decided to post a Marty Feldman video instead. (Yeah, go figure!) This is "Lightning Coach Tours," originally aired on the BBC on December 9, 1968, from Marty's Marty show, actually known as It's Marty (as of the time of the showing; this was the first episode from the second season, which used a different name for the series).
The coach driver ("Everybody back on the coach!") is John Junkin, who had a long, distinguished career as an actor, dying a little less than two years ago, on March 7, 2006.
