McIntire was responsible for a short, but important piece of paper that he inserted into copies of the Dead’s self-titled 1971 live album: “DEAD FREAKS UNITE: Who are you? Where are you? How are you? Send us your name and address and we’ll keep you informed. Dead Heads.”

That early effort of social networking, created by the former systems analyst for Fireman’s Fund Insurance, helped create one of the most loyal fan bases in rock history. McIntire managed the band during its creative zenith of 1970 to ’74.

After departing to manage Bob Weir’s solo career, he returned in 1984 and helped bring the Dead to the mainstream in 1987 with its Top 10 hit, “Touch of Grey.” He exited in 1990.
