Hollywood Docket Top 5: Pink Floyd vs. EMI; Joe Walsh vs. Joe Walsh; Music labels vs. 'Ellen'

• Pink Floyd is suing EMI Group over online royalty payments and the sale of single tracks. The lawsuit, filed in London, asks a court to clarify the band's contract with regards to the calculation of online royalties and whether tracks can be unbundled from the wider albums. [Business Week] 

• Former CBS News producer Robert Halderman pleaded guilty yesterday of attempting to extort $2 million from David Letterman. He was sentenced to six months in jail. Previously, Halderman unsuccessfully tried to have the lawsuit dismissed under the claim that he was simply selling Letterman rights to a book or screenplay. [CBS]

• Politician Joe Walsh has removed a campaign video that contained a song by the Eagles band member also named Joe Walsh. We wrote about the funny letter that the attorney for the musician sent to the congressional candidate. Afterward, the political candidate responded with his own letter that tried to be funny, accusing the musician of letting "leftist" Hollywood-think affect enjoyment of a parody. Nevertheless, Walsh, the Republican, seems to have backed down. [Citizen Media Law Project]

• Last September, we reported that several of the biggest record labels were suing producers of "The Ellen DeGeneres Show," claiming the show was violating the copyrights on thousands of song recordings. At least five of those record labels withdrew their claims in court this past week. The rest of the case has been transfered to California District Court for the convenience of the parties, and in particular, Jonathan Norman, who is primarily responsible for the music used on the show.

• Producers of "Iron Cross" are upset that Variety's editorial staff published a negative review of the film after its sales staff sold them on an Oscar promo campaign. [Read the complaint]
