The main theme of The Piano is a Tannahill song called "Gloomy Winter's Noo Awa'," and the main theme of Brassed Off is "The Dalesman's Litany."

A Mighty Wind has no actual folk songs in it, and indeed no parodies of folk songs; there are only parodies of songs written in the 1960s. But there were two traditional song parodies cut out of the film: "Corn Wine," a John Barleycorn-type thing, and "Killington Hill," a brutal murder ballad. Look for them on the DVD!

"Songcatcher" has some good performances.
