I sing this song frequently acapella, at the Fleece in Bretforton(Worcs) . I first heard Shep sing it at a P.O's mess bash, many years ago.. but for some reason the line ' grease in your pintles gone hard' often draws a snigger from the landlubbers and for me ruins the seriousness and feeling of the song, so I sing 'gone bad' instead.
-a lovely song
