The Black Crowes send their wishes to Page for a healthy recovery and hope fans will understand. Tickets for canceled shows will be refunded at the point of purchase�.. It is possible, if Page's recovery permits, that he and The Black Crowes will reschedule shows in New York and perform in Japan in December. "
