Here I am in Camp Grenada
Returning briefly to an earlier posting on the subject first posed by Michael Blowhard and later picked up by Terry Teachout of lost performance art forms, a couple more cross my mind.
The novelty song album. To a large extent this was carried on by Wierd Al Yankovitch, but it reached its height in the sixties with Alan Sherman. There was a time when I, as a young lad, practically wore the grooves off of My Son the Folksinger and My Son the Celebrity.
Another related form is the comedy album. Remember when comedy albums were a big deal? Some of my favorites were Bill Cosby's Why is there air?, Robert Klein's Child of the 50's, and George Carlin's Class Clown. Of course in my college years, Firesign Theater played with my head.
