I was rather fond of the Zo Elliot & Stoddard King composition "There's a Long, Long Trail" and so my partner and I learnt it from the John Roberts & Tony Barrand version, mentioned above in March 2001 by Meadow Muskrat.
We sang it for my late Mum on a visit home to Perth and she promptly burst into tears! She explained that her Mother had told her "It was your Father's favourite song!" He had died in 1926 from the TB he had caught as an Aussie Medical Orderly in WWI.
