I’m going to put 2+2 together. Peter Piper lives in Dublin. The name of this tune, the lack of any recordings to go with it, and the (perhaps tenuous) fact that Peter’s other submission around the same time was a self-penned tune, would suggest to me that this is also by him.
It’s an interesting jig, nothing special for me though.
Re: Port Debby
Peter Piper submitted this as "The Clontarf Lass". He obviously copied it from Treoir, Volume 5, Number 1, 1973, where it was followed by an obscure reel called "The Clontarf Lass". He evidently mistook the title of the reel for that of the previous jig, "Port Debby". So, Tøm, your 2+2 here doesn’t make 4!
