Sorley MacLean
Sorley MacLean (; 26 October 1911 – 24 November 1996) was a Scottish Gaelic poet, described by the Scottish Poetry Library as "one of the major Scottish poets of the modern era" because of his "mastery of his chosen medium and his engagement with the European poetic tradition and European politics". Nobel Prize Laureate Seamus Heaney credited MacLean with saving Scottish Gaelic poetry.

Additionally, a manuscript compiled in Scotland in 1816 by the MacLean-Clephane sisters was discovered in 1983 and includes at least five other pieces credited to Carolan and other annotated pieces that were "improved by Carolan" or "consistent with Carolan's writing to warrant consideration". These airs are included in the Appendix of the 2001 edition of "Carolan: The Life Times and Music of an Irish Harper" along with detailed research notes. These pieces came to light a decade after the death of Donal O'Sullivan in 1973, so he never had an opportunity to subject them to the same analysis that he used on the original 214 airs that he originally compiled in 1958. However, to date, no one has disputed the attributions presented in this manuscript. Newly composed harp arrangements for each of these and all the other airs (as well as new Carolan repertoire numbers 215 to 226 for each of the MacLean-Clephane tunes) are included in "The Complete Carolan Songs & Airs" by Caitríona Rowsome. The five pieces that are said to be composed by Carolan rather than simply "improved" are:
