Tribute Festival took place in Ballyshannon, County Donegal from Thursday May 29 until Sunday June 1. On Friday May 30, Celine Dion played Croke Park, Dublin on her fortieth birthday with support from Il Divo. Also on Friday May 30 at 9 a.m., tickets for Morrissey's June 28 show at the Royal Hospital, Kilmainham went on sale. Humanitarian rock stars Bono and Bob Geldof guest edited the Friday May 31 edition of the Asahi, Japan's second largest newspaper.
