G'day Lyle,

It may well depend on nationality and service, but the songs of the type quoted by USN vet are, at least in Australia (and, to the best of my knowledge, in the British forces), usually sung to John Brown's Body (or Battle Hymn of the Republic). It certainly is a portmanteau lyric, using whatever is appropriate from the last version - and making up new verses to cover today's situation.

Regards,

Bob Bolton
