It's become an over-used punchline--as in "Don't expect Republicans and Democrats to hold hands and sing 'Kumbaya " Google has 89,000 citations of the phrase.
But here's the thing. Although I learned 'Kumbaya' at summer camp in 1960, (but didn't discover it meant "Come By Here" for a couple more years), and I sang along with it at concerts throughtout the 60s, I don't remember ever HOLDING HANDS and singing "Kumbaya."
What's your recollection?
