Lullaby lyrics

Go to sleep It's getting late My watch says It's half past eight In an hour I must go When I'll be back Well, I don't know While I'm gone You'll be the man Help your mama When you can It's a big job I can see For a boy Just pushing three Son can I have A little kiss Just a small one You won't miss That's right close Your sleepy eyes You shouldn't see Your daddy cry So go to sleep It's getting late My watch says It's half past eight In an hour I must go When I'll be back Well, I don't know
