At their performance at Sunrise, Florida’s BB&T Center last night, the members of Dead & Company (the Grateful Dead project featuring John Mayer) showed support to Marjory Stoneman Douglas High School, the site of the February 14 shooting in Parkland, Florida that left 17 people dead. Working with Florida Congressman Ted Deutch, Dead & Co. invited teachers, students, and parents from the school to the show and brought them backstage afterward. The band also wore t-shirts that read “MSDStrong” while on stage. See a photo of them backstage above, and scroll down to see the shirts. Dead & Co. recently announced a summer tour.
