We're in a class war and songs of social significance can raise our spirits and resolve for the good fight. Plus the sounds of some San Francisco Bay Area bands that were formed 60 years ago. No, the Grateful Dead weren't the only band to come together in 1965. Just ask a Jefferson Airplane fan. It was a significant year in Bay Area music and culture. And, yes, a few songs for Memorial Day, including Phil Ochs' "One More Parade."
