(CBS News) While the "So You Think You Can Dance" Top 10 will all be going on tour, two of them had to leave the show on Wednesday.

One more male dancer and one more female were eliminated after the hopefuls danced their first routines with the all-stars.

Sitting on the judges' panel with Nigel Lythgoe and Mary Murphy was Benjamin Millepied, who choreographed the film "Black Swan" and is now married to its star, Natalie Portman.

Some of the highlights of the evening included a contemporary routine from Eliana Girard and all-star partner Alex Wong; an acrobatic, lift-filled disco number from Tiffany Maher and Brandon Bryant; a sultry jazz routine by Witney Carson and first-season winner Nick Lazzarini; and an emotional contemporary number from Cyrus "Glitch" Spencer and all-star Jaimie Goodwin.

A playful Bollywood number danced by Will Thomas and Kathryn McCormick also earned praise from the judges as did the hip-hop routine from Chehon Wespi-Tschopp and Lauren Gottlieb and the Fosse-inspired Broadway routine danced by Lindsay Arnold and Jakob Carr.

Others were not so lucky. Cole Horibe struggled in his cha-cha with Anya Garnis, and Lythgoe told George Lawrence II he didn't believe his character in the Broadway routine he danced with all-star Allison Holker.

After everyone danced, the bottom four were revealed to be Witney, Audrey, George and Chehon. All four were asked to perform solos.

Ultimately, the judges - who Lythgoe said were "not unanimous" - decided to save Witney and Chehon, which meant Audrey and George were sent home.
