"Yeah, my my grandmother was a war bride, after the Second World War. She met Bob Cain, he was an American sailor. And they met in Perth, and after a very brief engagement, married and then he was sent away. She received a telegram at about midnight one night, saying eh pack your things, there’s a train, ah the US Navy is chartering a train to take ah war brides to Sydney, and from Sydney you can board a ship, and we’ll take you to America to be with your husbands, and I just wonder how those women must have felt as they were journeying across their country possibly for the last time you know to go and live in this, in this new place and you know with children, and you know I was…I get a bit emotional still when I sing that song."
The Bridal Train EP was released in March 2004 and made the Australian Top 50 singles charts in April 2004. The song Bridal Train won the first prize in the 'Folk' category, as well as the overall first prize, in the 2006 USA Songwriting Competition.
