I take your point Jon. I must admit, I have always wondered why on earth Dave Richardson chose the key of E for this tune. Want to know how we play it? I sing the Rocky Road to Dublin (in E minor) with the A part of the Swallowtail Jig in between each verse, then we play the whole of the Swallowtail Jig at the end, and then straight into Calliope House. The modulation from E minor to E major works wonderfully, the audience loves it.Murray
