Funeral procession? Memorial vigil? Adelphi and Dekalb 11/11

Last night around 8pm I was walking up Adelphi towards Dekalb when I noticed 2 groups of people walking slowing, singing, and some holding candles and flowers. Some were walking on Dekalb, others up Adelphi and met at the corner by Red Bamboo.

Anyone know what was going on?
Sounded like a funeral procession.

If it was a group of Mexican people I saw the procession on Myrtle and Waverly and wondered about it too.
