[spoken]
At this time I should like very much to admire you all for schlepping out here tonight

[sung]
So long, sad times
Go long, bad times
We are rid of you at last
Howdy, gay times
Cloudy gray times
You are now a thing of the past

Happy days are here again
The skies above are clear again
So let's sing a song of cheer again
Happy days are here again

All together, shout it now
There's no one
Who can doubt it now
So let's tell the world about it now
Happy days are here again

Your cares and troubles are gone
There'll be no more from now on
From now on

Happy days are here again
The skies above are clear again
So, let's sing a song of cheer again
Happy times
Happy nights
Happy days
Are here again
