Scotty McCreery and Lauren Alaina will take the stage tonight for an all-country American Idol finale that pits two very young singers against each other; combined, they are only 34 years old.

What can viewers expect from these two, aside from three songs apiece?

• Carrie Underwood has selected a single for Lauren, while George Strait has done the same for Scotty.
• The other two tracks will be chosen by the producers and by the contestants themselves, who pick their favorite from the season.
• The Edge and Bono will perform on tomorrow night's results show, but not with U2. Instead, they'll be hyping the June 14 opening of the controversial Broadway production Spider-Man: Turn off the Dark.

We'll rundown tonight's performances first thing in the morning, but it's not too soon to chime in: Who do you think will win?
