“Cory Lingner … [is] using the app to tap alongside some of the most iconic movie stars, including Gene Kelly, Gregory Hines, Ann Miller and Shirley Temple. And, no, he doesn’t have a time-traveling device. Lingner has perfected the use of the app’s duet feature. On one side of the video is a clip of the tap-dancing icon and on the other is Lingner, dancing in unison.” – Dance Spirit
