This tune is Irish in style but may have originated in the US before its spread through much of the traditional music world. It is also known as a hornpipe named Katherine Brennan's Favorite, which came from Irish-American fiddler Andy McGann, who learned it from his fiddle teacher Katherine Brennan.
