IAN BROWN is singin' those jailhouse blues again, after his appeal from a four-month sentence for threatening behavior on an airplane was denied. His UK tour, scheduled for November, has now been rescheduled for after his release. In the U.S., his long-delayed "Unfinished Monkey Business" album has been pushed back yet again, this time to early 1999. It is doubtful he could tour the U.S. until around April or May of 1999. Meanwhile, OASIS frontman Liam Gallagher had another run-in with "The Man" earlier this week after reportedly smashing up a photographer's camera. Liam was released without being charged. The Oasis b-sides compilation, "The Masterplan" is released this week in the U.S.
