British music superstars Paul McCartney and Robbie Williams have joined forces in a battle over the United Kingdom's copyright laws. At issue is the fact that under the British statute musical recordings expire after 50 years. The United States copyright law for music is 95 years and that is what artists in Britain want the law to be extended to. This would be a major blow to The Beatles as many of their first hits will expire starting in the year in 2012.
