You get to thump on Home Boys Home, and clap at The Wild Rover, but my personal favorite Uunhh is Man Piaba - the one that Harry belafonte did on what was the first record my parents bought as a couple. It's about trying to figure out the birds and bees. The chorus I hear in his very West Indian voice is:
Hey! Woman piaba and the man piaba
And the tam tam call but the lemon grass
The lily root, golly root, belly root UUUNH!
And the famous randy scratch scratch.

No points for guessing my favorite line... and as a child, I just LOOOOVED singing about that famous randy scratch scratch!
