Let's Dance: An Earth Protection League Short Story
Dean Wesley Smith loves writing Earth Protection League stories. Old people in space, saving the Earth. Since he’s old, this provides wonderful dreams for Dean.
He wrote this story especially for Robert Jeschonek’s wonderful anthology SPACE:1975 that came out in January of 2021.
And, of course, science fiction with 1975 tropes, the Earth Protection League must save Earth from a giant disco ball. What else?
