How do I sing and play without setting up another player?

The instruments are each an individual player, and all 3 vocal parts fall under the 1 vocals player. The lead vocals set the difficulty for all the vocal parts, and the harmonies basically add points to your score. To answer your question, you cannot sing without setting up another "player" but all you need is a regular controller to use to select vocals difficulty for each song. It can be a guest rather than have a gamertag, but you wont get vocal achievements/trophies or anything.

Yes. i was hoping my local Gamestop would have a midnight opening, but no luck. Not sure how useful I'm being at work right now with all this in my head.
