final version

Played by Bob Weir with the Grateful Dead and with most of his other bands.

I went down to the mountain, I was drinking some wine
I looked up into heaven, lord I saw a mighty sign
Writ in fire across the heaven, plain as black and white
Get prepared, there's gonna be a party tonight

Chorus
Uh huh, hey, Saturday night
One more Saturday night
Hey, Saturday night

Everybody's dancing down at the local armory (note 1)
With a basement full of dynamite and live artillery
Temperature keeps rising, everybody getting high
Come the rocking stroke of midnight, the whole place is gonna fly

[chorus]

I turn on Channel Six, the President comes on the news
Says I got no satisfaction, that's why I sing the blues
His wife says don't get crazy, Lord you know what to do (note 2)
Just crank that old Victrola, put on your rocking shoes

[chorus]

Then God way up in heaven, for whatever it was worth
Thought he'd have a big old party, thought he'd call it planet earth
Don't worry about tomorrow, Lord, you'll know it when it comes
When the rocking, rolling music meets the rising, shining sun

[chorus]

(1) variations Bob Weir has sung include "Everybody's dancing at the local skating rink" (thanks to Dan Franzen for spotting this)
(2) on 17 April 1982 (and perhaps on other occasions during Ronald Reagan's presidency), Bob Weir sang "Nancy says don't get crazy Ron, you know just what to do."
