Here's a list of the songs Pace is most likely to hear when fighting against going to sleep (which is pretty much every night these days).  I know it's not a very diverse list but hey, why fight the classics?

In order:

1. "Beautiful Boy" - John Lennon
2. "Golden Slumbers" - The Beatles
3. "Tell Me Your Dream" - Blue Rodeo
4. "St. Judy's Comet" - Paul Simon
5. "Goodnight" - The Beatles
6. "Innocent When You Dream" - Tom Waits
7. "Be My Baby" - Ronettes
8. "Don't Worry Baby" - Beach Boys
9. "Dark Angel" - Blue Rodeo
10. "Train in the Distance" - Paul Simon

...and then whatever pops into my head beyond that.  If you'd like some more diverse ideas, here are some  threads on AskMetaFilter that cover this theme.

I don't do a lot of "audience participation" threads but would love to hear what your kids/nieces/nephews/babysitting charges liked and/or what songs you think might be good as lullabyes?
