Patti LaBelle turned out some impressive moves during this season of Dancing with the Stars, but in an exclusive clip she shows off the voice that made her famous in the first place.

Performing her 2004 hit "2 Steps Away" was just a warm-up for LaBelle, 70, as she prepped for "Most Memorable Year" night on DWTS. That night, she would earn a solid 30 out of 40 points traveling back to 1973 and performing a jazz routine to her hit “Dan Swit Me.”

Partner Artem Chigvintsev is just one of LaBelle’s castmates, including Derek Hough and Suzanne Somers, watching in awe as the legend freestyles with the show’s house band, Ray Chew Live.
