Good song for ESL class?

I teach at a junior college, and I know that a number of ESL instructors select rhyming songs that alternatively emphasize the articulation of consonants and vowels. You could contact the heads of any college in the states teaching ESL, or you can visit their websites and look for their on-line ESL links. There are too many to mention here, but you can try www.sjcc.edu and look for the ESL department and e-mail one of the instructors for tips. Publishers also have ESL exercises on-line.
