What about "Never Wed An Old Man" (He's got no faloorum....)
and Eric Bogle's "And The Band Played Waltzing Matilda" about the Australian soldiers at Gallipoli - particularly this verse:

And now every April I sit on my porch
And I watch the parade pass before me
And I see my old comrades, how proudly they march
Re-living old dreams and past glory
And the old men march slowly, old bones stiff and sore
The tired old heroes of a forgotten war
And the young people ask, "What are they marching for?"
And I ask myself the same question.

(the storyteller, of course, cannot march as he lost both legs at Gallipoli)
