VERSE

What do the sirens scream for?
Why all the crowd ?
What do the lights all gleam for?
Horns toot out loud?
Traffic is so terrific,
Mobs making noise,
Out near the old Pacific
Girls tell their boys,

 REFRAIN

"Come and wear your white tie,
It's the right tie,
For tonight I meet you
At that noisy, girlsy and boysy
Hollywood Party."
 
All the minks and sables,
Wine with labels,
Garbo-Gables,
Greet you.
Taxi send us
To a tremendous
Hollywood Party .
 
All the girls wear ermine coats they got from men,
And tomorrow they must give them back again
Let the laughter spring out,
Music ring out,
Satan sing out, "Hot-cha,''
At that crashing,
Furniture-smashing
Hollywood Party.
