One of Paul Jung's greatest successes as a Producing Clown was his Army Gag, a fixture of postwar American circus clowning both on Ringling (where Jung himself did it) and on other shows (where others adapted it).
I'm not sure who the tramp in the front of the photo is or who is about to have his paper-mache head knocked off (this head was displayed, unlabeled and unidentified in the Ringling Museum of the Circus in Sarasota when I visited there in 1997) in position number two but they are followed by Jung himself, Prince Paul Albert and Gene Lewis. If you look to the left I believe that is Dennis Stevens in the distance.
The gag was performed to great acclaim for about 20 years (1945-1965) but died out due to two unfortunate factors, Jung's untimely death in 1965 and the Vietnam War.
It's unlikely that it would be revived anywhere but Ringling today since no American shows currently tour with a large enough and/or capable enough Alley.
I believe Irvin Feld put an official moratorium on the gag when he purchased the Ringling circus, one that has held throughout the Feld "stewardship" of that show. I don't see any reason for the moratorium to continue today as support for our troops here at home is almost universally unquestioned and the characters don't necessarily HAVE to be soldiers. They could be Boy Scouts, Girl Scouts, police, firemen, ushers, security guards, life guards, janitors, circus ring crew or just about anything.
Change the Army fatigues for Boy Scout uniforms, the guns for shovels and 90% of the gag could be done with no objection or controversy tomorrow.
