about Stuart's post:
this song was originally a song about a soldier's return where his family is wondering whether he is their lad.
the same song was also sung by students where the mother is asking about his coloured cap, his father about his mustache, and his sister about his scarred gashes.
I don't know which one is older, but who cares? I sing both as a former soldier and student.

Sing and enjoy
