I've got that CD, Blow, Boys, Blow, and the version of Banks of Newfoundland on it doesn't sound at all like the tune to The Star of the County Down to me, unless there is another Star of the County Down.The tune I know as The Star of the County Down is the one sung by Roger Whittaker, which is pretty much the one that Van Morrison did. Pub bands sing this tune all the time so the arrangement must be fairly common.
