Mystery Science Theater Alive! was a series of live Mystery Science Theater 3000 performances.
The first was presented at the Uptown Theatre in Minneapolis, Minnesota on Friday July 10, 1992 at midnight with a family matinee the following day, Saturday July 11, 1992, at 11:30am.
During the show, Joel and The Bots riffed the film World Without End. This was a fully-produced live version of Mystery Science Theater 3000, with the cast appearing in-character (including Mike Nelson as Jack Perkins). It was done as an experiment to test for the possibility of a live tour. Instead of original host segment breaks, the cast performed sing-a-longs to old favorites, such as "Godzilla Genealogy Bop", "Tibby, Oh Tibby", "(Let's Have) A Patrick Swayze Christmas", and an MST3K-inspired cover of Lou Reed's "Satellite of Love".
The second was performed as part of ConventioCon ExpoFest-A-Rama on Saturday, September 17, 1994 at the State Theatre in Minneapolis, Minnesota.
The film riffed was This Island Earth, later riffed in Mystery Science Theater 3000: The Movie and, again, was performed in character with host segments and songs, concluding with a rendition of "Satellite of Love".
Clips from both versions can be seen in The MST Scrapbook.
