A jig that I wrote a number of years back sounds very Irish, but because I wrote it on a January 25, I called it "Robbie Burns Day". I played it a few times at a local session and I started hearing that it was being played sessions in other cities. When I Googled it, I found a very professional sheet of music for my tune credited to "Joe Yates". I contacted the person who published it and he made the changes.
It has been recorded twice; once by a Peterborough group called "Freshwater Trade" and once by a wonderful fiddler, the late "Zeke Mazurek".
There was even a question on Mudcat asking about who had written the tune.
