A Lincolnshire Posy, considered Grainger's masterpiece, was composed for concert band in 1937. The work is composed of six movements, each adapted from folk songs that Grainger had collected on a 1905–1906 trip to Lincolnshire, England. Grainger maintained the personality and quirks of each singer he heard on his trip, creating a a musical portrait of the singer's personality and musical style.
 
The Lost Lady Found is a straight ahead 3/4 time theme and variations, and final movement of Lincolnshire Posy.
