(Lennon/McCartney)

They say it's your birthday
It's my birthday too, yeah
They say it's your birthday
We're gonna have a good time
I'm glad it's your birthday
Happy birthday to you

Ah
Ah
Ah
Come on
Come on

Yes we're going to a party party
Yes we're going to a party party
Yes we're going to a party party

We're gonna have a good time
