Any one know some great jazz songs that are not too over kill with millions of key changes, because I am new to jazz playing, but I don't want simple jazz either if there were ever such a thing.

I have been playing quite alot of guitar for some time now so I can play complex but not to the extreme of lead playing over many keys, its very difficult to grasp it.
Take 5. It's up on here, and it's very nice.
