Hi Leeneia,
Sorry nobody got back to you right away. Don't give up on us. First of all, let me say that if you start a thread and no one responds it will creep off the list, but it has not gone away. You can search for it again and refresh it by replying to it yourself with a simple message saying "refresh." That will pop it back to the top of the list again for a while.
Secondly, be patient. Sometimes finding tunes can be more difficult that finding actual songs with words.
Thirdly, there are many, many wonderful tunes out there. There are quite a few lovely mazurkas out there. And a goodly number of those are called Donegal Mazurka. Why? Because Donegal is one of the places where the Mazurka thrives in Ireland. (The mazurka is a musical import from Norway, Sweden or some such place. It is a slightly waltz-like tune similar to the hambo. Am I wrong about this 'Catters?) Would it be possible for you to supply us with more than the very few details that you gave us, so we can identify this tune? I know of one such named tune on a recording by Altan called Island Angel. Could this be the one?
