Bye Bye Birdie---Put On A Happy Face
Thanks to Julia James for submitting the lyrics
(From "The Beginning" Episode | Used During: The scene at the nuclear power plant as Homer gets eaten)

Gray skies are gonna clear up
Put on a happy face
Wipe of the clouds and cheer up
Put on a happy face

Take of the gloomy mask of tragedy
It's not your style
You'll look so good that you'll be glad
That you decided to smile

Pick out a pleasant outlook
Stick out that nobel chin
Wipe off that full of doubt look
Snap on a happy grin

Spread sunshine all over the place
And just put on a happy
Put on a happy face

Gray skies are gonna clear up
Put on a happy face
Wipe off the clouds and cheer up
Put on a happy face

Take of the gloomy mask of tragedy
It's not your style
You'll look so good that you'll be glad
That you decided to smile

Pick out a pleasant outlook
Stick out that noble chin
Wipe off that full of doubt look
Snap on a happy grin

Spread sunshine all over the place
And just put on a happy
Put on a happy face
