Last week (ends25JUN04), Bowie cut short a concert in Prague, Czech Republic, because of pain in his shoulder. Earlier this month (JUN04) in Oslo, Norway, he was struck in the eye by a lollipop thrown from the crowd, but wasn't hurt.
Organisers of the festival say in a statement, "This morning David Bowie's physician informed us that (his) condition doesn't enable him to carry through the planned concert."
A statement on Bowie's website says the cancellation is "due to David's continued condition".
Bowie was scheduled to perform on Friday (02JUL04), the first day of four-day outdoor event.
