The Weavers revised the lyrics somewhat when they played their final Carnegie Hall concerts in December, 1980.

From the 1981 album The Weavers - Together Again:

CHORUS:
How do I know my youth is all spent
My get up and go has got up and went
But in spite of it all, I'm able to grin
And think of the places my get up has been

Old age is golden, so I've heard it said
But sometimes I wonder as I fall into bed
With my teeth in a cup, and my wig in a drawer
And I hope my glass eye doesn't roll on the floor
As sleep dims my vision, I say to myself
Is there anything more I should put on the shelf?
First Carter, now Reagan, I surely am vexed
But I'll still stick around to see what happens next

CHORUS

When I was young, my slippers were red
I could kick up my heels right over my head
Then I grew older, my slippers were blue
But still I could dance the whole night through
Now I am old, my slippers are black
I huff to the store and I puff my way back
But never you laugh, I don't mind at all
I'd rather be huffing than not puff at all!

CHORUS

I get up each morning and dust off my wits
Open the paper and read the obits
And if I'm not there, I know I'm not dead
So I eat a good breakfast and roll back to bed

CHORUS

Pete Seeger sang solo on the first chorus. Fred Hellerman sang the first verse, Ronnie Gilbert the second, and Lee Hays (who was now in a wheelchair) sang the third.

One of my favorite songs, which I find I appreciate more and more the older I get.
