Sonny Brogan's (catch-all for unidentified tunes)

Several different Irish traditional tunes go by this name. These can be searched for in:

• MusicBrainz,
• Irish Traditional Music Tune Index (curated by Alan Ng, with bibliography and very reliable discography),
• Traditional Tune Archive (collaborative, with many printed references and some recorded references), and
• The Session (collaborative, with broadest coverage but lesser printed references and least reliable discography).
