The brothers soon found themselves in regular conflict with CBS 's network censors . At the start of the 1968/69 season , the network ordered that the Smothers deliver their shows finished and ready to air ten days before airdate so that the censors could edit the shows as necessary . In the season premiere , CBS deleted the entire segment of Belafonte singing " Lord , Do n't Stop the Carnival " against a backdrop of the havoc during the 1968 Democratic National Convention , along with two lines from a satire of their main competitor , '' Bonanza '' . As the year progressed , battles over content continued , including a David Steinberg sermon about Moses and the Burning Bush
