Yes, Laoise, Pesach and Seder are correct. I love Pesach -- especially the singing. And the food. If you're interested, I'd be happy to send you the Four Questions written in the style of Dr. Seuss. But since it's not really a song, I didn't think I should post it here.

Re: The Irish Ballad: the little lass did away with her mother not with a suicide bid, but with a "cyanide soup she planned."

And she drowned her father in the creek due to a fit of pique (which is sort of like having a small tantrum), rather than a fit of peak.

Shel Silverstein also wrote a marvelously tongue-in-cheek chauvinistic song called "Put Another Log On The Fire," which I think is in the database.
