The Beatles
"Birthday"

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

Bridge--

Yes we're going to a party, party
Yes we're going to a party, party
Yes we're going to a party, party
I would like you to dance (Birthday)
Take cha cha cha chance (Birthday)
I would like you to dance (Birthday)
Oh, yea

(Repeat Bridge)

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