I found this thanks to Bob Fish at a UK Autoharps Day. Great song, one of very few that mention harps, appropriately for me. I sang it at a few folk clubs. Mostly it was totally new to the audience, but it certainly stirred a few of the "old-timers" who came up to me after with memories of their dad's singing this song after pub on Sunday lunchtime and suchlike. This link lets you hear Frank Luther and his pards singing it.
