"You've Had a Birthday! Shout Hurray!"

You've had a birthday! Shout hurray!
We want to sing to you (Paco) today (yesterday)!
One year older (inevitably) and wiser (maybe that's why you didn't believe me when I said, "Hey, look out the window! The llamas wrote 'Happy Birthday' in dung!") too.
Happy Birthday (clap) to you!
