The story outline is pure Gilligan: the castaways are stranded,
Gilligan finds parts of a rocket which the Professor assembles. The
Howells help write a note to put in the rocket nose-cone, with island
coordinates given by the Skipper. The girls (especially Ginger) help
"motivate" the Skipper to peddle a rocket launching device to speed
(as seen on photo above). The rocket is seen by a group of
extraterrestrial aliens as being the launching of a wartime device.
They come to "destroy the earth" but are dissuaded by Gilligan as he
explains how the castaways (from all different "walks of life") have
learned to all live together...in peace.
Of course, that's just a basic outline. There are a lot of additional
adventures building huts, exploring caves (see photo left) and much,
much more. We strongly recommend it as good, wholesome, family
entertainment.
The music is fantastic and is well combines with the castaways
adventures and we learn more about how the characters feel concerning
themselves and each other; such as the Professor's frustrations at
not being able to devise a workable rescue plan. (Incidentally, due
to a "Gilligan" malfunction, the rocket that the castaways launch
crashes back on the island!)
Unfortunately the Musical is no longer running.
