From this morning's Guardian:
"Ari Up, frontwoman of the celebrated British post-punk band the Slits, has died at the age of 48.
The singer, born Arianna Forster, passed away yesterday (20 October) after a "serious illness".
The announcement was made by representatives of Forster's stepfather, John Lydon, last night. A statement on his website reads: 'John and Nora have asked us to let everyone know that Nora's daughter Arianna (Ari Up) died today after a serious illness. She will be sadly missed. Everyone at JohnLydon.com and PiLOfficial.com would like me to pass on our heartfelt condolences to John, Nora and family. Rest In Peace.'"
