Twenty-nine years ago this week, the Grateful Dead performed “I Will Take You Home,” a Brent Mydland song written with Bob Weir friend and collaborator John Perry Barlow, for the last time in a concert at what then was known as Foxboro Stadium outside of Boston. Mydland, the band’s third full-time keyboardist and the longest-tenured in that role, would be dead less than two weeks later following a narcotic overdose at his California home. Mydland was a passionate performer, and his songs seemed to take a more raw, confrontational approach to emotional subjects like spousal separation and parent-child relationships than the often more opaque offerings of his bandmates. “I Will Take You Home” is a song about a father trying to protect and encourage his daughter, and its final performance is this week’s Jam (with bonus Jerry-in-shorts footage):
