They played Creedence Fortunate Son at his elaborate birthday party slash military parade.
For those who aren't old enough to know, the song is about rich people buying their way out of the Vietnam War.
"Some folks are born silver spoon in hand
Lord, don't they help themselves, Lord?
But when the taxman come to the door
Lord, the house lookin' like a rummage sale, yeah
It ain't me, it ain't me
I ain't no millionaire's son, no, no
It ain't me, it ain't me
I ain't no fortunate one, no"
