Spinal Tap is a made-up English heavy metal band created by the comedians and musicians of The T.V. Show on the American commercial broadcast television network ABC. The 1984 mock documentary film This is Spinal Tap gave a dramatised fictional history of this parodic band, which satirises in its image, sound, and lyrics some of the biggest bands of the New Wave of British Heavy Metal. The soundtrack of the film was released on March 2, 1984.

Its second track, the song “Tonight I’m Gonna Rock You Tonight,” parodies an affair between a man and a little girl who is four feet high and still has her baby teeth. Here is a musical video of the song, from YouTube:

Here are the lyrics from Genius:

Tonight I’m Gonna Rock You Tonight

Little girl, it’s a great big world
But there’s only one of me
You can’t touch cause I cost too much
But tonight I’m gonna rock ya (Tonight I’m gonna rock ya)
Yeah, tonight I’m gonna rock ya (Tonight I’m gonna rock ya)
Tonight!

You’re sweet but you’re just four feet
And you still got your baby teeth
You’re too young and I’m too well hung
But tonight I’m gonna rock ya (Tonight I’m gonna rock ya)
Yeah, tonight I’m gonna rock ya (Tonight I’m gonna rock ya)
Tonight, whoa yeah!

You’re hot, you take all we got
Not a dry seat in the house
Next day, we’ll be on our way
But tonight I’m gonna rock ya (Tonight I’m gonna rock ya)
Yeah, tonight I’m gonna rock ya (Tonight I’m gonna rock ya)
Tonight!

Little girl, it’s a great big world
But there’s only one of … Me!
