Bay seniors looking for role models who just get better as they get older might do well to ponder the career of Leonard Cohen. At 80 he’s still recording and his “Hallelujah” appears to be becoming this generation’s “God Bless America”. Lucky us have the Bay Area’s Conspiracy of Beards a 40-man a capella group exclusively focused on Cohen’s 4 and 5 part harmonies. They’ve been around since 2003 performing the master’s beautifully lugubrious songs in full Cohen gear – suits and tie’s and the occasional fedora. You can catch them this month in San Rafael and San Francisco and next month in Redwood City.
