You say yes, I say ...

You say ... and I say go, go, go
Oh, no
You say ... and I say hello
Hello, hello
I don't know why you say goodbye
I say hello
Hello, hello
I don't know why you say goodbye
I say hello

I say ... , you say low
You say why, and I say I don't know
Oh, no
You say goodbye and I say ...
Hello, hello
I don't know ... you say goodbye
I say hello
Hello, hello
I don't know why you say goodbye
I say hello
