Problem: Background: Sergio Santos Mendes (Portuguese pronunciation: ['seRZju 'satuZ 'medZiS]; born February 11, 1941) is a Brazilian musician. He has over 55 releases, and plays bossa nova heavily crossed with jazz and funk. He was nominated for an Academy Award for Best Original Song in 2012 as co-writer of the song "Real in Rio" from the animated film Rio. Mendes is married to Gracinha Leporace, who has performed with him since the early 1970s.
Context: Mendes was born in Niteroi, Brazil, the son of a physician. He attended the local conservatory with hopes of becoming a classical pianist. As his interest in jazz grew, he started playing in nightclubs in the late 1950s just as bossa nova, a jazz-inflected derivative of samba, was emerging. Mendes played with Antonio Carlos Jobim (regarded as a mentor) and many U.S. jazz musicians who toured Brazil.  Mendes formed the Sexteto Bossa Rio and recorded Dance Moderno in 1961. Touring Europe and the United States, Mendes recorded albums with Cannonball Adderley and Herbie Mann and played Carnegie Hall. Mendes moved to the U.S. in 1964 and cut two albums under the Sergio Mendes & Brasil '65 group name with Capitol Records and Atlantic Records.  Sergio became full partners with Richard Adler, a Brooklyn-born American who had previously brought Bossa Tres plus two dancers, Joe Bennett and a Brazilian partner, to appear on The Ed Sullivan Show, in 1963. He was also accompanied by Jobim; Flavio Ramos, and Aloisio Olivera, a record and TV producer from Rio. The Musicians Union only allowed this group to appear on one TV show and one club appearance (Basin Street East) before ordering them to leave the U.S. When the new group, Brasil '65 was formed, Shelly Manne, Bud Shank and other West Coast musicians got Sergio and the others into the local musicians union. Adler and Mendes formed Brasil '65, which consisted of Wanda Sa and Rosinha de Valenca, as well as the Sergio Mendes Trio. The group recorded albums for Atlantic and Capitol.
Question: Why were they ordered to leave the US?

Background: The Smothers Brothers are Thomas ("Tom" - born February 2, 1937) and Richard ("Dick" - born November 20, 1939), American singers, musicians, and comedians. The brothers' trademark double act was performing folk songs (Tommy on acoustic guitar, Dick on string bass), which usually led to arguments between the siblings. Tommy's signature line was, "Mom always liked you best!" Tommy (the elder of the two) acted "slow", and Dick, the straight man, acted "superior".
Context: With its focus having evolved toward a more youth-oriented one, the show became both popular and controversial. Three specific targets of satire -- racism, the President of the United States, and the Vietnam War-- wound up defining the show's content for the remainder of its run, eventually leading to its demise.  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, Don'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.  With some local stations making their own deletions of controversial skits or comments, the continuing problems over the show came to a head after CBS broadcast a rerun on March 9, 1969. The network explained the decision by stating that because that week's episode did not arrive in time to be previewed, it would not be shown. In that program, Joan Baez paid tribute to her then-husband, David Harris, who was entering jail after refusing military service, while comedian Jackie Mason made a joke about children "playing doctor". When the show finally did air, two months later, the network allowed Baez to state that her husband was in prison, but edited out the reason.  Despite the conflict, the show was picked up for the 1969-70 season on March 14, seemingly ending the debate over its status. However, network CEO and President William S. Paley abruptly canceled the show on April 4, 1969. The reason given by CBS was the Smothers' refusal to meet the pre-air delivery dates as specified by the network in order to accommodate review by the censors. This cancellation led the Brothers to file a successful breach of contract suit against the network, although the suit failed to see the brothers or their show returned to the air. Despite this cancellation, the show went on to win the Emmy Award that year for best writing. The saga of the cancellation of the show is the subject of a 2002 documentary film, Smothered.  Highlights from seasons two and three of the show have been released on DVD, but there is no explanation of why anything from season one remains unreleased.
