Okay, so the song is really simple to learn and the song and reprise are almost the same.
Verses:
Michael Rennie was ill
The Day the Earth Stood Still
But he told us where we stand.
And Flash Gordon was there
In silver underwear,
Claude Rains was the Invisible Man.
Then something went wrong
For Fay Wray and King Kong.
They got caught in a celluloid jam.
Then at a deadly pace
It Came From...Outer Space.
And this is how the message ran
Chorus:
Science fiction, double feature
Doctor X will build a creature.
See androids fighting Brad and Janet
Anne Francis stars in Forbidden Planet
Woah oh oh oh oh
At the late night, double feature, picture show
And you just repeat that ^_^
Also, for the reprise, replace all the Cs with Fs
