Derek Hough Shared BTS Video of Making 'Disney Family Singalong Vol 2' Performance

Derek Hough and Hayley Erbert perfected another performance for the Disney Family Singalong Volume II on Sunday night (May 10).

The couple were joined by his sister Julianne, who dressed as Mary Poppins, for their “Step in Time” and “Supercalifragilisticexpialidocious” numbers.

“Here’s a little look behind how we made the video,” Derek shared on Instagram. “Hayley figured out how to multiply ourselves. But it took an insane amount of trial and error since we really had no idea what we were doing. We filmed and edited it ourselves which took us a long minute. Thank you @abcnetwork @disney for the invitation :) Always grateful for the opportunity to create 👍🏼🕺🏼 #gopro”

If you didn’t catch their performance, it will be available to stream on Disney+, starting on Tuesday (May 12)!
