Skyline High School’s production of “Joseph and the Amazing Technicolor Dreamcoat” started this week. (The photo was shot during a rehearsal.) You can still see it at 2 p.m. and 7:30 p.m. tomorrow and 7:30 p.m. next Thursday through Saturday. If you go, you’ll see Skyline actors, dancers and musicians — and performers from Oakland’s Bret Harte and Montera middle schools. You can find more info here.
