LOS ANGELES? - Mick Jagger will take to the Web on Thursday to announce details of the Rolling Stones' summer tour of Europe, a spokeswoman said.

Jagger, who will be in London, will reveal the itinerary and take questions from European media outlets at 4 p.m. GMT (noon EDT). The webcast can also be viewed by the public.

It was originally envisaged that the whole band would talk about the tour during a traditional news conference at a London hotel, but U.S.-based guitarist Keith Richards was unable to make it, according to a source close to the band.

The trek is expected to include cities that were pulled from the itinerary of last year's tour after Richards hurt his head while on vacation in Fiji. Additionally, two Spain shows were scrapped at the last minute when Jagger came down with a sore throat.

According to the well-connected fan web site It's Only Rock'n Roll (http://www.iorr.org), the tour will likely include a June 10 stop at Britain's Isle of Wight festival, while shows are rumored for such cities as Athens, Barcelona, Belgrade, Brussels, Bucharest, Chorzow, Copenhagen, Duesseldorf, Gothenburg, Helsinki, Lisbon, Lyon, Madrid, Nijmegen, Oslo, Paris, Rome, San Sebastian, St. Petersburg, and Zagreb.
