I'm Tickled Pink

 (composed by Jack Shaindlin) is a song which can be listened to in Fallout 3 if you tune in to Galaxy News Radio.

Lyrics
I'm tickled pink That things are rosy And skies are blue once again

Let the bygones go bye-bye No more will I sigh or cry

I'm tickled pink The moon is yellow And I'm your fellow tonight Soon we'll greet that red-letter day When I will pop the question And you say OK Say then we'll be married in the month of May

Repeated one more time
