Steve Roud has posted a request for this song,(admitting that even he doesn't know of it!) on the UK Ballad list. Dick Greenhaus suugested that a query on mudcat might yield a result - so this is a challenge!
Steve's query was:(as it had been passed on to him)

"Do you happen to know a song, possibly barrack-room in origin, that begins:"

All the little angels rise up, rise up,
All the little angels rise up high.

It goes on "Feet up, feet up high" and works through various parts of the body till it gets to "Arse up, arse up, arse up high."

Does anybody recall this? It sounds as if it goes back to the days of National Service, if not before.
