I don't remember exactly how many NaNa's there were in the song. It was the late 60s and I wasn't born, yet. Ok, I was born, but I was really little and I loved Batman.

I would run around the house with a towel pinned around my neck and jump off the furniture singing NaNaNa...Batman!
Imaginary Batman has come a long way. The things I could have done if I had these kinds of props.
