"Come, Sweet Lass", also known as "This Bonny Weather" is an English air in F Major. The parts are played AB. The melody appears under this title in John Gay's Beggar's Opera (1729) and earlier in all editions of Thomas D'Urfey's Wit and Mirth; or, Pills to Purge Melancholy (1698) and is associated with the 18th century theatre. It appears in Playford's Dancing Master from the 9th edition through the last (18th) edition where it is known as "Greenwich Park". There is an English manuscript source from c. 1704-1707 and an undated songsheet that attributes the music to a "Mr. Clarke". Scots composer James Oswald (who lived in London) included the tune in his 1744 collection A Second Collection of Curious Scots Tunes. It was entered into the music manuscript copybook of London musician Thomas Hammersley (c. 1790). It was printed in Aird's Selection of Scotch, English, Irish and Foreign Airs, vol. 3 (1788), Chappell's Popular Music of the Olden Time, vol. 2 (1859), Oswald's Caledonian Pocket Companion, Book 2 (1760) and Raven's English Country Dance Tunes (1984). It was recorded by Abby Newton on Castles, Kirks and Caves (2001).
