Yes I have a verb song which has the whole irregular verb 'to be ' in it.
You can find it on my site http://www.thejemsite.com and it is called 'Verbs, Verbs, Verbs' (naturally :lol. The song is a contemporary rock ballad and is fairly generalistic about what verbs are and gives examples of them. However it does have the entire 'to be' verb in it...since it is rather special.
I'm not sure whether this would be something you are interested in or not. The song is set within the context of Australian football (Aussie Rules) and so has some Australian colloquialisms in it as well. Though it was intended to help young Australian boys understand what verbs are and how to use them, I'm sure there may be something in there that others might like.
My site is a kind of i-tunes for teachers but also offers free teaching materials with each song. I hope this helps.
If there is something you need which isn't there, you could always put in a request and I'll write one for you and put it up on the site.:-D
