Lyrics
"You are old, Father William," the young man said
"And your hair has become very white
And yet you incessantly stand on your head
Do you think, at your age, it is right, is right?
Do you think, at your age, it is right?"
"Well, in me youth," Father William replied to his son
"I'd do it again and again"
