But, I Can't Sing

Freddie smiles but doesn't move one way or another. You sit gingerly on the couch next to him. He's small and willowy. His bass guitar is bigger than his torso and head combined. He begins to speak softly and you have to lean forward to hear what he's trying to say.
"-ided that you should go on tour with us. As, as, a backup, yeah?" He stares at you, you stare at him. You don't want to ask him to repeat himself because that's awkward. But you also don't want to say nothing at all so you just say.
"Yes."
The whole band smiles at you and you suddenly realize... you have no idea what you agreed to.
