There's an ad running on a local radio station (KPOJ 620 AM in Portland) for a St. Patrick's gathering, and the music for this ad is fiddlers playing "Angelina Baker" - the tune I hear bluegrass and fiddlers do often.   
This made me wonder if this tune has Irish origins. (Or does whoever put the ad together, or the fiddler group themselves, think that anything with fiddles can pass for "Irish music?"
