Twinkle Twinkle Little Star

It looks like Lennon may be a Mozart fan.  We've recently discovered that he prefers 'twinkle twinkle little star' over other songs.  He doesn't like if you change the rhythm or tempo at all.  He's a purist.  He doesn't even seem to respond the same to the ABC's, which is the same melody even.  He's such a funny little guy.  He's been in such a good mood lately.
