American Idol American Idol

Before American Idol's dreaded green-mile segment, the remaining contestants are going to have to travel a little bit more than a few hundred feet to determine their fate. On Wednesday, the top 40 competitors will travel to Las Vegas to pay tribute to The Beatles. The biggest obstacle: choosing what to sing from the Fab Four's diverse catalog. We match some of the show's most recognizable standouts with their best song choices.

Casey Abrams: After blowing judges, and fans, away with his bass performance last week, Casey is riding high on momentum and has enough added stage presence to wow with either a slower tune like "Hey Jude," or a faster tune such as "Get Back."

Haley Reinhart: Minus her speed bump during the group round, her soaring vocals have helped Haley stand out from the beginning. To make it to the next round, it's time for Haley to switch it up and bring her octave range to a faster tune such as "Revolution." 

Carson Higgins: His high-energy performances and penchant for screaming, rather than singing, some of his lyrics, makes a loud single like "Help!" or "Eight Days a Week" a good fit for Carson.

Thia Megia: The time has come for the soulful 15-year-old to branch out and explore something slightly more mainstream. Maybe she could try something from their early years like "Can't Buy Me Love" or "I Want to Hold Your Hand."

Road trip! Is American Idol headed to Sin City?

Chris Medina: From his memorable first audition, the 26-year-old has been one of the few guys to really hit the high notes. Combine that with his less-than-stellar performance of the faster "My Prerogative" and a wide-ranging (not to mention emotional) ballad like "Across the Universe" is his best bet.

Jacob Lusk: There's never been any doubt about his impressive vocal range, but Jacob is in great danger of losing the judges' interest once and for all with his oversinging. Jacob is in need of something much more up-tempo that also gives him room to really belt — for example, "A Hard Day's Night."

Lauren Alaina: This 15-year-old has relied on the radio-friendly ballad "I Don't Wanna Miss a Thing" one too many times, so it's time for her to venture off — way off — the beaten path. Maybe something like "Strawberry Fields Forever" or "Lucy in the Sky with Diamonds."

John Wayne Schulz: This Texas cowboy has remained very close to his comfort zone of simple country ballads. Though not a huge stretch, it would be nice to see John lend his deep baritone to the classic "Let It Be."

Clint Jun Gamboa: This karaoke host first wowed the judges with his soulful take on "Billionaire," but it was his electric rendition of "Georgia on My Mind" during Hollywood Week that really solidified him as one to watch. Clint should pick a slower hit like "All You Need is Love" to give him room to show his range.

American Idol airs Wednesday at 8/7c on Fox.
