I did say that you're allowed a little rehearsal. And I said 'sing' not perform. This means songs that you know the chorus and at least the first verse or two.

For instance, most of us know 'Kathleen' and could sing it. But just because you may need a refresher on the second verse, it doesn't mean that you don't know the song.

Sorry I didn't make that clearer. So go for it.
