Those ’60s flower children are back with the patched jeans, long stringy hair and even a little tie-dye. Appropriately, though, you’ll have to thread your way through a group of 21st-century anti-establishment “hippies” in Civic Theatre Plaza to get to them.

Broadway San Diego presents the touring company of the 1967 musical “Hair” to Civic Theatre through Sunday. It’s outside the theater that Occupy San Diego protesters have taken up residence, and if you go out at intermission, you’ll hear their version of “Aquarius” or some other song from “Hair.”
