My nieces and I found this on youtube the other day:

It's a rare clip of the Dixie Cups performing "Iko Iko" live on TV. It brought back a lot of memories (not only of this particular song, but of watching shows like this when I was a kid).

The interesting thing about this song is that the arrangement uses only vocals and percussion. In the studio version, without handclaps from the crowd, it sounds like the only instruments used were drum sticks (struck against each other) and a floor tom (or something similar)for the bass line.
