"The Moon's A Window To Heaven" was a song which Uhura sang under the moons of Nimbus III as she performed a fan dance for the resident guards of Paradise City. Her dance seduced the entire lookout party and they were lured into a trap. After which, she laughingly told them, "Hello, boys. I always wanted to play to a captive audience!" (Star Trek V: The Final Frontier)
Lyrics[]
The drums of misted hearts
Are carried on the air
I can hear my name
From out there somewhere
The moon's a window to heaven
For the eyes of lovers below
The moon's a window to heaven
It's there that I want to go
I will dance away
Beneath a starry dome
I will find a way
To fly to my home
The moon's a window to heaven
For the eyes of lovers below
The moon's a window to heaven
And it's there I someday will go
Silver light
Against an endless night
I feel the rapture
Captured in flight
The moon's a window to heaven
For the eyes of lovers below
The moon's a window to heaven
It's there that I want to go
The moon's a window to heaven
For the eyes of lovers below
The moon's a window to heaven
Music for the song was written by Jerry Goldsmith with lyrics by John Bettis. (Star Trek Encyclopedia, 4th ed., vol. 2, p. 52)
The version as heard in the film features vocals performed by Margaret "Machun" Sasaki-Taylor (Star Trek V: The Final Frontier expanded soundtrack liner notes), despite having been promised to Nichelle Nichols. (Beyond Uhura) Machun also performs the soundtrack version, performing with the band Hiroshima.
The history of the song was discussed in further detail on StarTrek.com. [1]
