As well as "The D-Day Dodgers " (attributed to Lance-Sergeant Harry Lynn, 78th Infantry Division,Italy,1944 and "Collected" by Hamish Henderson )there is also the amusing "Bloody Orkney" by Hamish Blair.Of more recent origin and enjoyed by British sailors is "Rubbish ! I'm RDP ! " by Shep Wooley circa 1970s ; "RDP" stands for Run Down Period , when naval ratings (enlisted men) who are asked to sign on for another five years invariably exclaim "Rubbish ! I'm RDP !"
Nobody seems to have mentioned the lovely "Travelin' Soldier" ; brings tears to my eyes every time.
