Mark Mendoza was bassist for Dictators, not Dead Boys. I believe bassist Jeff Magnum is far right in this pic. Jimmy Zero's name is missing from the list of members.
What year was this show? Fri. Jan 29th doesnt make sense. In 1977, Jan 29 fell on a Saturday, in 78 a Sunday, in 79 a Monday, in '80 a Tuesday. Maybe it's a typo and its suppose to be Friday Jun 29 1979
