I was just planning my civil ceremony and can't have the date in September I would like, but wanted a memorable one and thought of this song and 'the last day of September' so looked this song up as it sparked some memories.   My wonderful mum taught this to me in the 1960's - 1970's and she was from The Mumbles in Swansea, South Wales. She was born in 1938 and I'm guessing learnt it at school herself in Wales. I'm sure our version went 'the good ship' not the big ship. I can't ask her as sadly she is no longer with us. I think we sang it at school too.
