Why is this? Why "currently not displayed"?
I found a great performance on Youtube: "Joan Osborne, Stevie Wonder and Keith John perform Marvin Gaye's "I Heard It Through the Grapevine" at the 1996 Rock & Roll Hall of Fame Induction Ceremony."
To my surprise it wasn't in the database, so I collected the data, Discogs, Spotify, and added the Youtube URL. "Go to Edit Videos to view the videos associated with this performance, but currently not displayed." It's quite discouraging.
