"It's a Nice Place to Visit"

According to Andrew Sandoval's The Monkees: The Day-by-Day Story of the 60s TV Pop Sensation, "It's a Nice Place to Visit" - the thirty-third episode of The Monkees series (and the first of the second season) - was broadcast fifty years ago to-day (11 September 1967).  It was written by Treva Silverman, directed by James Frawley, and featured the song "What Am I Doing Hangin' 'Round?"  Sandoval describes the plot as: "A trip to Mexico goes south when the evil El Diablo captures Davy."
