No the Creggan WH is not related. However there are at least 3 songs in the Holme Valley Beagles booklet of songs which obviously are set to the WH tune and inspired by the song. I would guess this means that the song was well-known and very popular in West Yorkshire in the late 19th century. The earliest version if I remember correctly was set in Maxwelton in the Scottish borders, but hunt meets/suppers often had guests from other hunts so songs would move about in hunting fraternities freely.
