Vivian Williams let me know in the comment on one of the posts that the tune that Erskine called the Liverpool Hornpipe is in fact a tune Don Messer recorded called The Victory Breakdown. Apparently, the first parts are very similar and this could explain Erskine's confusion of the title.
As well, the tune we labeled Erskine's Hornpipe for the sake of having one less "Unknown" title for is indeed a well-known tune in Quebec and Canada that goes by several different titles such as Reel de\à Remi, Reel de Saint-Jean, and Reel de Ti-Jean, Gordon's Reel, and the Chamberlain. Joseph Allard played this tune calling it L'Hôtielier. Jean Carrignan played this tune very well also. Erskine was a big fan of both Allard and Carrignan and was known to pick up tunes off their recordings.
