My Mum used to sing this to my son to get him to sleep when he was a baby and it never failed!

Abe, Abe, Abe my boy
What are you going to do now
You promised to marry me one day in June
It's never to late and it's never too soon
All the family
Keep on Asking me
Which day, what day, I don't know what to say
Abe, Abe, Abe my boy, what are you going to do now
