Okay, so I've jumped into this discussion WAY late, but I'm about to be making a tape for some friends to play to our guinea pig, Harry, while we're away on vacation of me singing his favorite lullabyes (to which he always quits whatever he is doing and settles down and YAWNS really big several times!). I sing to Harry just before saying goodnight to our daughter (his cage is in her room); and even when I sang "Lullabye and Goodnight" to our daughter, I never knew all the words and just either hummed the last part or made up something like: I don't know, any more words, so you're stuck, with half a tune. I hope you're asleep, by the time I end, or into nightmare land, my rhymes will send. But Clueless Don's version really is so very close to what I remember from my own childhood. The first half is identical except we always sang "AND start to yawn" and the second half I like so much, I'm going to commit it to memory and begin using it all the time! Thanks!

Lullaby, and good night
go to bed now and sleep tight
close your eyes, and start to yawn
pleasant dreams until the dawn

when the sun lights the sky
you'll awake feeling high
start your day with a smile
life is always worthwhile
