THE Rolling Stones have been forced to drop four "sexually explicit" songs from an upcoming Shanghai performance (08APR06) after coming under the scrutiny of Chinese officials. The rock legends - who were censored just over a month ago during their Superbowl half-time performance of START ME UP - axed Brown Sugar, HONKY TONK WOMAN, LET'S SPEND THE NIGHT TOGETHER and BEAST OF BURDEN from their repertoire because the songs were deemed unacceptable by China's Ministry Of Culture. The Shanghai stop on their A BIGGER BANG tour would mark The Rolling Stones first ever performance in China. They were scheduled to tour Asia in 2003, but shows were cancelled amid fears of the SARS (Severe Acute Respiratory Syndrome) epidemic.
