Climb up on my knee, Sonny Boy
Though you're only three, Sonny Boy
You've no way of knowing
There's no way of showing
What you mean to me, Sonny Boy.

When there are grey skies,
I don't mind the grey skies.
You make them blue, Sonny Boy.
Friends may forsake me.
Let them all forsake me.
I still have you, Sonny Boy.

You're sent from heaven
And I know your worth.
You made a heaven
For me here on earth.

When I'm old and grey, dear
Promise you won't stray, dear
For I love you so, Sonny Boy.

When there are grey skies,
I don't mind grey skies.
You make them blue, Sonny Boy.
Friends may forsake me.
Let them all forsake me.
I still have you, Sonny Boy.

You're sent from heaven
And I know your worth.
You've made a heaven
For me here on earth.
