Merry melodies

Must admit that it was harder to find a list of happy (happy not just love songs) songs than it was to think of depressing ones. What does that say?
Here is a list of what I consider to be cheery/happy/sing-along-with songs:
Yellow submarine - Beatles thought these characters were cute, or All you need is love etc.
Wake me up before you go-go - Wham
Is this love - Bob Marley or One love
Time warp - Rocky Horror
Don't worry, be happy - Bobby McFerrin
You are the sunshine of my life - Stevie Wonder
Good vibrations - Beach Boys and just about any Beach Boys song
If you're going to San Francisco - Scott McKenzie
Push-bike song - Mixtures try doing this in Melbourne now-days
I am Australian - Seekers ending with something patriotic and uplifting!
