The first tune in the set was composed by Scottish musician and tutor Nigel Gatherer, the Crown being a hotel in the town of Portpatrick in south-west Scotland where Nigel stopped off for a meal! The second tune was originally by Mozart and I am told it is numbered KV536 No2. It seems it was made popular by Michael Turner who was a church fiddler in Sussex in the 19th century. It also was used in the 2020 film Emma.
