Oops, I forgot the link for the last song. You can listen to it here: https://www.youtube.com/watch?v=Pub65C8h8Vw

This song, titled "Medicare - Billy Sol" is a medley of two songs, "Medicare" and "Billy Sol." The first one is obviously about Medicare, set to the theme of "Oh Christmas Tree." "Billy Sol" refers to businessman Billie Sol Estes, who is best known for a business scandal that sent him to jail for fraud multiple times and complicated by his ties to friend and future U.S. President Lyndon Johnson.

MEDICARE - BILLY SOL
(Wini Beatty)

Oh Medicare, sweet Medicare
Everyone deserves a share
So go fall on your derriere
Send the bill to Medicare

Go strain your sack, 'roiliac*
Have a big fat cardiac
Why be a healthy lunatic?
You're crazy if you don't get sick

Oh Medicare, sweet Medicare
Treats you like a millionaire
Get clobbered on the thoroughfare
Medicare will be right there

Of course the treas'ry shows a loss
It costs you much more than Blue Cross
But what a pleasure to be ill
And never know you paid the bill

[tempo change to "Billy Sol"]

Did you lay some dough away, Billy Sol, Billy Sol?
Did you lay some dough away, Billy Sol Estes?
Did you hide what they say you stole for
The day you get your parole

Go ahead, hibernate
Let that int'rest accumulate
You're still young, you can wait
Billy Sol Estes

* "Roiliac" probably refers to the joint disease Sacroiliac.
