What do I say after he says he will go with me to Sadies?

I left a note in my friend's locker asking if he'll go to sadies with me but he wasn't here today but I guess he came after school and saw it but I wasn't there. So he told my friend he said yes but he wants to tell me personally tomorrow. So when he says he'll go with me to Sadies...what do I say after that doesn't sound cheesy?
