All Souls Church, Unitarian

I'm going to All Souls Church, Unitarian (1500 Harvard Street, NW) tomorrow to meet with the archivist, Mara Cherkasky, to look at their 1968 materials.  All Souls is one of the most progressive churches in the city.  David Eaton, who transformed the church, did not start his tenure as senior minister until 1969.  However, church discussions with him started in 1968 so I'm hoping to find a letter to/from him, as well as other materials that document the church's activities in 1968. 

Do you recognize anyone in this photo?  Did you participate in the march?  Or do you remember hearing about or seeing the march?  If so, please leave comment.

It looks like they are walking south on 16th st, on the east side, alongside Malcolm X park, just a few blocks from All Souls.
