Ahem ... having already provided the Beatle and skewbald parts of the links on fRoots (and I do inhabit both of these forums ... fora?) and just established the link .... The song "Stewball" - ie the misspelled horse, ie should have been Skewbald (as in the Martin Carthy version of the song) has chord and melody structure virtually if not totally identical to the tune of Happy Christmas (War is Over), performed by John Lennon (the mis-spelled Beetle/Beatle) and the Yoko Ono band.
