This was not actually an episode of "The Monkees", but rather a music special aired a year after the series ended. Like the movie "Head", the special illustrated how boxed in the guys felt by the series, and represented their attempt to do something they really wanted to do. Each Monkee had a showcase with music he chose, and there was a large lineup of guests, including Little Richard, Fats Domino, Jerry Lee Lewis, the Buddy Miles Express, and Brian Auger & Julie Driscoll with the Trinity. It is really nothing like "The Monkees", and is probably only interesting to hardcore fans of the group.
This tv special is extremely horrible. This is by far the worst of anything I have ever seen related to the Monkees. Avoid it at all costs. It has no central plot, no good songs or anything. The movie "Head" made no sense but was a very good movie. You aren't going to get that lucky again with 33 and 1/3.
