Someone here is the culprit
When I find out, you're through
Someone here is the culprit
Who? Who? Who?

It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
It could be you
(You could be the guilty one...)

One of you pulled a fast one
Went and made a switch
One of you pulled a fast one
Which? Which? Which?

It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
It could be you
(You could be the guilty one...)

It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
It could be you
(You could be the guilty one...)
It could be you, couldn't it? Couldn't it?
It could be you, couldn't it? Couldn't it?
Could it be you?
