I haven't thought of Alan Sherman since I was in elementary school. I used to listen to the album My Son the Folk Singer all the time at my grandmothers house. Sir Greenbaums Madrigal was my favorite.

Back to the topic...here is a version of that we used to sing in Minnesota.

Jingle bells, Batman smells
Robin laid and egg
Joker turned around the corner
......

Can't seem to remember the last part of it.
