... Just ran across a class action lawsuit that’s been filed by the few surviving original Delta and Chicago blues artists, along with relatives and estate representatives for dozens more who are deceased.

The suit alleged copywrite infringement by numerous original Delta and Chicago blues artists deceased or otherwise — to wit, that the defendants “stole” song structures without giving credit or royalties to the original writers.

The case is being called by legal scholars and entertainment lawyers as one of the most perplexing ever filed in the United States for one big reason.
