I recall watching a variety show in the '70s and some male vocalist who had been popular in the '40s or '50s was singing "Bad, Bad Leroy Brown," and at the end he added a stupid verse that was like "now he's nice, nice, Leroy Brown..."
Then there was either Johnny Carver or Johnny Duncan who recorded "Country Party," a bastardization of Rick Nelson's "Garden Party." Nelson recorded his song as a somewhat scathing response to being invited to "oldies shows" that only wanted him to sing his hits and nothing else. This was lost, of course, in "Country Party."
Sample lyric:
"Someone opened up the closet door
and out stepped Johnny Cash,
Playing guitar like a ring of fire,
And June was singin' in the back (Jackson)..."
