TORONTO could learn from this. For the first time in years, the San Francisco Opera, Ballet and Symphony along with smaller theatre groups and organizations have formed a united front in the quest for cash from City Hall. And it appears to be working. They got a boost of $7-million in additional funding – the largest increase in years.  GLENN McCOY, executive director of the San Francisco Ballet: “City Hall has given us a pretty clear message that until the arts community comes together in a unified and co-ordinated fashion, we are always going to struggle with how the city supports us . . . I don’t think it’s going to all be kumbaya right away, but we’ve got to change the direction. That’s what we’re trying to do right now. There are decades of rivalry and perceived rivalry that we are going to have to work through.”
