I concur Giles, also "Pell Mell Swells" is also, again my opinion, an acted "posh" accent of Pall Mall Swells, Pall Mall being the nub of British high society up to and probably into the 20c, up to the end of 19c in the British army your officer seniority was from the day you were gazetted, the date that your promotion appeared in The Pall Mall Gazette. 2BS&S (unbridled self promotion!)have a version which I assembled from the broadsheet and used the Johnny Collins melody, It is on "Crossing the Pond". I suppose it might be on the myspace site, dunno cos I found it so difficult when it changed i gave up on it
