Maestro John, if you will,please.
You say it's your birthday* 
It's my birthday too--yeah {
Not really, actually - next month}
They say it's your birthday
We're gonna have a good time
I'm glad it's your birthday
Happy birthday to you.
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
You say it's your birthday
Well it's my birthday too--yeah {
Not really, but soon}
You say it's your birthday
We're gonna have a good time
I'm glad it's your birthday
Happy birthday to you.
Hope you have a most excellent birthday.
