The Three Ds try to sing "By the Light of the Silvery Moon" during the pre-show film for Muppet*Vision 3D, but they mangle it badly and are stopped by Scooter.

The song was also performed by two penguins and two chickens in a video produced for Disney's Muppets.com website, and played on the Haunted Holidays page for Halloween.

Shadow sang part of this song as Bear tries to find her in the Bear in the Big Blue House episode, "And to All a Good Night." After Shadow's story, Bear and Shadow sang it again to gently wake up Tutter so he won't missed the special party.
