Wow, how weird that I came across this tonight. I rarely use the "new posts" button, but here I am vegging out.
I say that it's weird because my 2.5 year old has recently started to LIKE me singing to him (he used to not let me), and he likes to hear new songs, not just the same old ones. So I tried this song the other day, and this is as far as I got:
Hush little baby, don't say a word
Mama's gonna buy you a mockingbird
And if that mockingbird won't sing
Mama's gonna buy you a diamond ring
And if that diamond ring don't shine...
Mama's gonna have to smack your behind
(Laughing from both of us as I tell him that's not really how it goes, I just made that part up because I don't know the rest.)

So thanks! I am going to print this out and learn it now.
