Came across the following song in the Bodley Ballad collection, and thought it looked a bit familiar:

Sarah, Sarah, or a Donkey cart made for two
Written by Harry Bedford

Chorus is

Sarah, Sarah, make up your mind now do
I shall go fair barmy if I don't get hitched to you
Come,don't be aggravating
There's a home for you awaiting,
And you can ride bymy side in a donkey cart built for two
