Dead & Company wrapped their historic three-night run in San Francisco’s Golden Gate Park Sunday, celebrating 60 years of Grateful Dead music with tens of thousands of fans. The concert series gave a major boost to local businesses.

Back when he was a teenager, before he was even a fan of the band, he found himself at a Dead concert in Berkeley in the 1980s, and soon, in 1989, started selling T-shirts. He followed the band on tour until “the demise of Jerry,” when the lead singer died in 1995 of a heart attack.
