The brothers soon found themselves in regular conflicts with CBS ' network censors . At the start of the 1968 – 69 season , the network ordered that the Smothers deliver their shows finished and ready for air ten days before airdate so that the censors could edit the shows as necessary . In the season premiere , CBS deleted an entire segment featuring 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
