Brian Rohan, the San Francisco “dope lawyer” who represented rock clients like Grateful Dead, Janis Joplin, Santana, Aerosmith, Boston, Jefferson Airplane, and Kris Kristofferson, has died at 84, Consequence of Sound reports. Rohan's rock career was opened by Grateful Dead in 1966 when he helped them organize their first album contract with Warner Bros. Several months later in January 1967, the police arrested nearly 100 people on charges of loitering and “being hippies” after the Human Be-In. Rohan brought the case to trial and won, getting all other charges dismissed. Rohan also co-formed the Haight-Ashbury Legal Organization that same summer and often set up a table in front of the band’s house where he offered service to live-in and walk-in clients alike who needed help. A story has it also that Rohan punched David Geffen for having his phone calls for clients ignored, earning the applause of “Jann Wenner, Paul Simon, Linda Ronstadt, and Leonard Cohen".
