Grey's Anatomy by Ron Tom/ABC Grey's Anatomy by Ron Tom/ABC

The cast of Grey's Anatomy might not be back on TV on our timetable (that would have been months ago), but they are appearing on stage to sing together for a good cause. Members of the ABC hit's ensemble are joining forces with Private Practice thesps to raise money for crew members who suffered financially due to the WGA strike.

On Feb. 29, the two casts will perform in Good Medicine, a benefit at UCLA's Royce Hall that Grey's boss Shonda Rhimes describes as "a little singing, a little funny, a lot of raising money." For L.A. locals (or non-local jetsetters) who want to attend, tickets are on sale now - and going fast. - Anna Dimond
