The Butterfly aka The Red Admiral Butterfly is based on Bob and Joan or Boban (or Bobbin) John, an older tune.
There is a mudcat thread about it from circa 1998.

This and no. 65 are clearly related to the Scottish Jacobite song air "Cam' Ye Ower frae France" and also to Tommy Potts's The Butterfly. The song includes a reference to "Boban (or Bobbin) John", a nickname of the Jacobite leader the Earl of Mar; as Boban John, the tune was in Robert Petrie's "Fourth Collection of Strathspeys, Reels and Jiggs" (1796).
