You do know all the words by heart. You walk up to the microphone and
join in.

The crowd goes wild--they assume that you are a guest celebrity visiting.
Just one they don't happen to know. The guards are forming at the back, too
nervous to storm the stage with all eyes on you.

Robby look over at you, clearly puzzled. You decided that he's cute even
when puzzled. He stumbles over a few words, but you fill them in for him
and soon you are both singing full strength. The song seems to last forever,
and you hit every word.

But the song ends eventually, and the guards are looker bolder each second
as the applause starts waning.
