One of the items in Wikidata is the song "Shama Lama Ding Dong". This song was first performed in the National Lampoon's Animal House and, the Band of Oz, won People's Choice Song of the Year at the 1995 Carolina Beach Music Awards.
Mark Davis does not have a Wikipedia article. But the trouble has been taken to provide him with a Wikidata item. Given that "best practice" has the link go to the disambiguation page where Mark is not to be found either, it was a fine moment to introduce the "Redwd" template. It does link to Wikidata and the Reasonator while keeping the link red.
This is a good way to revive the function of the red link. It does provide information that is specific to this Mark Davis and, it could be the start for someone to write the missing article.
I want to thank Magnus for creating the template and Multichill for adding the documentation.
