As a boomer, Weir checked many of the key boxes as he and the band matured: interest in yoga and Eastern spirituality, macrobiotic diet, environmental activism. But more important is that, unlike many in his cohort, he stuck with his chosen family even after it was no longer a whirling utopian acid fantasy.
