Jenny Lewis, as you may know, was the sweet red headed child actress who played Haley in the 1980's movie The Wizard.
She has recently (09/23/2008) released a fantastic solo album called Acid Tongue, Which you can listen to for free here (but you should really buy this album since it is fucking fantastic)
Jenny is also the lead singer of Rilo Kiley and released an album in 2006 called Rabbit Fur Coat with The Watson Twins > also amazing. (Happy is track number 4).
Happy by Jenny Lewis & The Watson Twins from the album Rabbit Fur Coat (also on repeat)
I'd rather be lonely, I'd rather be free I'm as sure as the moon rolls around the sea But I like watching you undress And I think we're at our best By the flicker by the light of the TV set
Cause I can't remember why I hated you Can't remember why I still do But I'm as sure as the moon rolls around you That I could be happy, happy Oh, so happy, happy Oh, so happy, so happy
They warn you about killers and thieves in night I worry about cancer and living right But my mama never warned me about my own Destructive appetite
Or the pitfalls of control How it locks you in your grave Looking for someone to be saved under my restraint So I could be happy, happy Oh so happy, happy Oh so happy, happy So happy, so happy
