The final performance show of 2008 has come and the top 4 remaining dancers — Stephen ‘Twitch’ Boss, Courtney Galiano, Joshua Allen and Katee Shean — performed Wednesday before viewers decide who will be crowned America’s Favorite Dancer (and take home $250,000 and get a featured role in Adam Shankman‘s next movie) on the 4th season finale of So You Think You Can Dance.

As if the competition wasn’t challenging enough with its regular partner switches and increasingly difficult choreography, the finalists — two of which were hospitalized over the weekend — were paired up as guy and girl, girl and girl, guy and guy and all four together during the marathon show.

Twitch and Courtney started off with a hip-hop performance choreographed by Tabitha and Napoleon Dumo. The dancers nailed every move and got into the characters that the creative piece demanded. Guest judge Mandy Moore called the performance “awesome.” The other judges agreed.

Next up, Katee and Joshua performed a contemporary homage to love choreographed by Wade Robson and set to John Mayer‘s “Slow Dancing in a Burning Room.” Mandy called the moment “beautiful and very honest.” Mary thought it was “absolutely beautiful” and Nigel Lythgoe called them “remarkable,” adding that there’s “nothing more magical than Wade’s choreography.”

Courtney and Katee then danced together as a pair of dolls (without the guys) in a Tyce Diorio Broadway routine to Rufus Wainwright‘s version of “The Trolley Song.” A tribute to Hollywood musicals with white umbrellas and pastel dresses, the dancers looked like they had a lot of fun with the piece and the judges noticed, commenting on their chemistry.

Hip-hop dancers Twitch and Joshua then got a chance to end their (friendly) rivalry when they took on a difficult Russian trepak together. Taking their breaking skills to Moscow, the guys leaped, hopped and spun to Tchaikovsky‘s The Nutcracker Suite. A thrilled Mandy called it “spectacular” and “insane.” Mary called it “one of the most fabulous numbers” she’s ever seen on SYTYCD. (Watch a clip of their performance).

Together again, Katee, in a stunning gown, and Twitch, in a James Bond tuxedo, took on one of Tony Meredith‘s fox trots to Michael Bubl ‘s “Feeling Good.”

Then, Joshua and Courtney had a final chance to shine as partners with a fast and technical jive that pushed them to the limit of skills and stamina. Despite visible exhaustion from the dancers, ballroom expert Mary applauded them for pulling off the difficult version of the dance. But Nigel found the performance disappointing and blamed it on exhaustion.

For a final treat of the night (and the season), the top 4 took on a high-flying, Scottish-inspired contemporary piece choreographed by Mia Michaels that ended the season in the most appropriate way — with a violin-pumping high note.

Thursday a winner will be crowned and the Jonas Brothers will perform on the finale of So You Think You Can Dance (8 p.m. ET on FOX). — Jed Dreben
