"The Gentleman Thief" is a tune used for a traditional ballad known as "The Crafty Farmer" in which a high-born thief attempts to rob a farmer of the price he had just gotten for selling a horse but is outwitted by the clever peasant. The tune is found in Bronson's The Traditional Tunes of the Child Ballads, Volume 4. This is another tune that Williamson describes as "a wild Northumbrian jig". He plays it together with "The Whistling Thief" in the English Songs section. It is a little unusual in that the second part is in 9/8 time. It was printed in Williamson's English, Welsh, Scottish and Irish Fiddle Tunes (1976). I learned it from Williamson's book.
