Happy Stewball (War is Over)

Lennon made it no secret that many (all?) of his songs were inspired by music he hard heard. This goes for the riff of I Feel Fine, the intro of Instant Karma, Come Together... and for most of Happy Xmas. Here, the inspiration derives from Stewball, an English traditional. Stewball was perfomed by man artists (such as The Greenbriar Boys, Lonnie Donnegan, Peter, Paul & Mary, Woody Guthrie), but the version by the Hollies (1968) appears to be the one for Lennon. Here's a mash-up of those 2 versions.
