Sir Reginald MacDonald
This tune in popular in Cape Breton. Not sure who wrote it.
The tune appears in The Skye Collection, and David Glen’s Edinburgh Collection of Highland Bagpipe Music.
The subject is possibly Admiral Sir Reginald MacDonald, but more likely Reginald MacDonald of Staffa (1777-1838), who was later known as Sir Reginald MacDonald Stewart-Seton of Touch and Staffa.
If the latter, it is possible that the tune was composed by his piper, Archibald MacArthur.
This tune can be found in the Cape Breton Fiddlers Collection from Cranford Publications.
