Just for interest: Fred Woods in Folk Review ih the 1970s used to run competitions, like limericks or clerihews summarising the plots of ballads.

One was to produce the shortest-ever folksong on the lines of "The Gallant Frigate 'Amphitryte', She sank in Plymouth Sound". One of the winners, I recall, was "The sun is shining, And the oggie-man's still there".
