Alison,Wouldn't it be strange if you were THAT Alison? A few more details might help. The Alison I knew was here in Sydney for about 9 months then returned to Ireland a couple of years ago (have you come back?). Fair hair, medium height and build. She gave me her spare set of Susato whistles as a parting gift. Does this ring a bell?
I haven't yet looked at the Jimmy MacCarthy website which someone mentioned somewhere, but maybe that's where the meaning of the lyrics might be found.
