I mention this only as it does't seem to have had a mention before. (and I chanced to sing it 2 nights ago)
From EFDSS book THE LIFE OF A MAN, Songs from the Home Counties Coll. by Ken Stubbs.
Page 84. Sung by George Townshend, Lewes, 1961
Different melody (I can't copy music) and very different but readily joined in chorus:
'Wi-ild rover, wild ro-o-ver, wi-ild rover no-o mo-ore,
And I never, never sha-all play the wild rover no more.'
(And no prodigal son verse)
