A blast from the past here, although apparently, they don’t drink it in the Congo. And for your further delectation, the lyrics:
Way down deep in the middle of the Congo,
A hippo took an apricot, a guava and a mango.
He stuck it with the others, and he danced a dainty tango.
The rhino said, “I know, we’ll call it Um Bongo”
Um Bongo, Um Bongo, They drink it in the Congo.
The python picked the passion fruit, the marmoset the mandarin.
The parrot painted packets, that the whole caboodle landed in.
So when it comes to sun and fun and goodness in the jungle,
They all prefer the sunny funny one they call Um Bongo!
