From the recording The Road Out of Town
"Childgrove," still popular at country dances, dates to around 1701 and appears in many English country dance collections, including Playford's English Dancing Master.
The Campbell referred to in "Campbell's Farewell to Redcastle" may be Captain Robert Campbell of Glenlyon, who led troops in the massacre of Glencoe Pass in 1692. Redcastle is a village on the north side of Beauly Firth, County Fraser, approximately 100 miles from Glencoe, whose castle was built in 1179 (it claims to be the oldest inhabited castle in Scotland). The tune has migrated into the old-time traditions, where it is known as "Campbell's Farewell to Red Gap."
