I seem to remember hearing a Royal Engineers version to the same tune as the Rugby song. the only part I can recall runs somethine like

"I saw a Colonel sitting on a raft, "I saw a Colonel looking bloody daft, "Hold him down 'til we get over, "Hold him down you pontooneers, eers, eers, eers,"

then back to the "Ay zumba, zumba..." bit

Just my two penn'orth
