Lyrics:

The five o'clock whistle's on the blink
The whistle won't blow and whadd'ya think?
My pop is still in the factory 'cause he don't know
What time it happens to be

The five o'clock whistle didn't blow
The whistle is broke and whadda'ya know?
If somebody don't find out what's wrong
Oh, my pop'll be workin' all night long

Oh, who's gonna fix the whistle?
Won't somebody fix the whistle?
Oh, who's gonna fix the whistle?
So my poor old pop will know it's time for him to stop

Ya ought to hear what my mommy said
When papa came home and sneaked into bed
And told her he worked till half past two
'Cause the five o'clock whistle never blew
