There's Groucho Marx's recording of "The Funniest Song In The World"
which by Graucho's admission ( per the sleeve information) he was proud to have made even after turning down other offers to make phonograph records.
A genuinely sincere example of what came from a friendlier world in a better time. IMNSHO
A record which could still be played to a child of this generation ,and a valuable lesson gently learned.
