Detroit Freaks Out With First Participatory Zoo Dance

The psychedelic dance concert, long an institution among San Francisco hippies, came to Detroit Friday and Saturday nights. Oct. 7th and 8th, at the Grande Ballroom, Grand River one block south of Joy Road. Judging from the enthusiasm of the crowd who made it, the venture was a success. It looks like this new form of entertainment is here to stay.
