It reminds me of a song I learned when I was a child. "If you're happy and you know it, clap your hands. If you're mad and you know it stomp your feet. If you're sad and you know it, say 'boo hoo'." Something like that. I took my 16 month old to a gathering where they sang this song, but replaced every "sad" and "mad" with "happy"! Happy happy happy! I thought it was so silly. What, are kids going to be traumatized singing about being mad or sad? 
Side note: I know this song also, but I've never heard it with anything but "happy" in it. Happy = clap your hands, happy = stomp your feet... I forget what the others are, obviously not happy = say boo-hoo, though.
IME it's supposed to be a joyful song with an easy rhythm and physical actions to engage the audience, which generally consists of young children. Also IME it's a religious song. I'm actually quite impressed there's a version of it that encompasses other emotions, but I would've said that was new version! 
We sang this song when I was little in our (Methodist) Sunday School. But as *thedudeabides* and Lynn say, it was all "happy".
If you're happy and you know it, clap your hands ... (clap, clap)
If you're happy and you know it, clap your hands ... (clap, clap)
If you're happy and you know it then your heart will surely show it
If you're happy and you know it clap your hands. (clap, clap)
Repeated for stomp your feet, and anything else we could come up with. But no range of emotions. Only happy. I guess Methodist children weren't allowed to be anything but happy.
