Has "reunion" become a dirty word in rock music? Stewart Copeland of the Police thinks not.

Weary critics might grouse about old rockers hogging the limelight, cashing out and repeating themselves for lack of fresh ideas. Nevertheless, Copeland's once-pioneering reggae-rock trio is on the road once more after last year's great reawakening. It's part two of a reunion run that the Police had successfully avoided for 23 years, and it's the latest in rock's sometimes exhausting string of comebacks, album tours and prolonged farewells.
