Good Morning lyrics

Good morning, good morning, good morning
And a very happy birthday to you
Susie sing happy birthday to Daddy
Happy birthday to you, happy birthday to you
Susie sing happy birthday to Daddy
Happy birthday to you
Now Daddy may not spend much time with us (Fuck off)
But I'm sure that he loves you a lot
Susie sing happy birthday to Daddy
He's the only daddy you've got (Fuck off)
Fuck off, but I'm the song that the trees sing when the wind blows
Fuck off, but, honey, I'm the starlight and I'm a rainbow
Susie sing happy birthday to Daddy
Happy birthday to you, happy birthday to you
Susie sing happy birthday to Daddy
Happy birthday to you
