Most Christmas songs Americans are used to hearing on the radio were published after 1929. But most Christmas songs they’re used to singing in church are older. Much of the traditional American repertoire is in George Rittenhouse’s World Famous Christmas Songs, with 74 carols and nativity songs “specially arranged for popular usage in community caroling, school, chorus, church and home”. First published in 1929, and reissued in 1957, it’s in the public domain in 8 days. #PublicDomainDayCountdown
