Of course! Your whole family can enter in the same video if you want! : ) It's the one account that wins any prizes, doesnt matter how many people are in the video. We've had entries already with even 3 people in them. The sound quality is perfectly perfect. : ) So please start thinking of next week! You can actually go ahead and record the video and just have it sitting till Thursday to upload. Then if something comes up along that way that would make you not be able to record it, it won't matter because it's already done : ) We suggest that to everyone because we want everyone to have a chance to enter even if available time is an issue. I have listened to Peter's song probably a dozen times in the past 2 days.
