Lyrics:

They say it's your birthday
Well, 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

(One, two, three, four, five, six, seven, eight!)

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 a cha-cha-cha-chance (birthday)
I would like you to dance (birthday)
Dance, yeah

Whoo
Come on

I would like you to dance (birthday)
Take a cha-cha-cha-chance (birthday)
I would like you to dance (birthday)
Whoo, dance, dance

They say it's your birthday
Well, 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
