Rob Roy can refer to the popular novel by Sir Walter Scott, published in 1817, as well as the shortened name for a number of stage dramatizations of the novel from 1818 onwards.

While the authors of the adaptations are not always credited (the play even credited to Scott in some instances), recognized stage versions which appeared in 1818 alone include:

Rob Roy Macgregor; or, Auld Lang Syne! by Isaac Pocock (1782–1835)[1], with music by John Davy ()[2].

Rob Roy MacGregor by Henry Murray[3]

Rob Roy, The Gregarach by George Soame

Performance history in South Africa

A play called Rob Roy MacGregor Campbell and said to be based on Scott's novel, was performed a number of times in the African Theatre, Cape Town by the amateur company English Theatricals in the years 1823-24. It is most likely that this was the widely known and published Pocock musical version, given that there is mention of "the original Overture and Music" on one occasion. However, it may have been the Murray version, which had been devised in association with Scott.
