"The Red Haired Boy", in Gaelic "Gilleruadh" or "Giolla Ruadh", the same title that results in another tune with the Englished title "Guilderoy". "Guilderoy" is usually set in A minor and this tune is usually set in A mixolydian. It is used for the song "The Little Beggarman".
The tune is an Irish, Scottish or English air or hornpipe. It is also known in the US and Canada as a reel or breakdown.
It was printed in Bégin's Fiddle Music in the Ottawa Valley (1985), Krassen's Appalachian Fiddle (1973), Messer's Anthology of Favorite Fiddle Tunes (1980), Miller & Perron's New England Fiddler's Repertoire (1983), Mitchell's Dance Music of Willie Clancy (1983), Moylan's Johnny O'Leary of Sliabh Luachra (1994), O'Neill's O'Neill's Irish Music (1915), O'Neill (Krassen) (1976), O'Neill Music of Ireland: 1850 Melodies (1903), O'Neill Dance Music of Ireland: 1001 Gems (1907), Phillips' Traditional American Fiddle Tunes, vol. 1 (1994), Silberberg's Fiddle Tunes I Learned at the Tractor Tavern (2002), Spadaro's 10 Cents a Dance (1980) and Sweet's Fifer's Delight (1964).
I play this tune in medleys with:
      "Guilderoy"
      "The Mason's Apron"
      "The Rights of Man"
all in this section.
I most often play it with "Guilderoy" as the two red haired boys go well together and the change of mode makes an interesting set (on mandolin, not on banjo).
