After at first seeming to slam the door shut on a plea by the National Academy of Recording Arts and Sciences to allow its annual Grammy show to proceed without pickets and with writers, the Writers Guild of America West appeared to open it a crack Tuesday, saying that the academy's latest request "will be referred to the WGAW Board of Directors for decision." The Screen Actors Guild indicated Tuesday that if pickets are posted at the awards show, it expects to show solidarity with the WGA and not participate in the ceremonies scheduled to take place in Los Angeles on February 10. However, most singers and musicians are members of AFTRA and the American Federation of Musicians and are expected to fulfill contractual obligations to perform on the show or act as presenters. The two unions released a joint statement Tuesday urging the WGA to allow the Grammys to proceed, pointing out that proceeds from the even sustain "important educational, charitable, and advocacy activities" of NARAS. The Grammys are scheduled to air on CBS.
