FILE - In this Nov. 20, 1987 file photo, then-Burlington, Vt. Mayor Bernie Sanders sings during a recording session in Burlington, Vt. Sanders, accompanied by a backup group of Vermont singers, background, was putting out a tape of five songs and a discussion of his philosophy that will be available in stores. Sanders feels music is a powerful way to communicate with the masses. Once a democratic socialist, always a democratic socialist. Once a scold of big money in politics, still a scold. No one can accuse Sanders of flip-flopping over his four decades in public life. Rock steady, he’s inhabited the same ideological corner from which he now takes on Hillary Rodham Clinton in an improbable quest for the Democratic presidential nomination.
