Penned by John Perry Barlow and composed by Bob Weir, “Cassidy” was partially dedicated to Cassidy Law, born in 1970 to Eileen Law, one of the Grateful Dead’s early archivists, and Neal Cassady, who passed away in 1968. After its debut in 1974 at Cow Palace, “Cassidy” remained a fixture in the Dead’s setlists, with over 300 performances during their touring career.
