Bob was approached by Nick Cenci and Nick Kousaleous, local Pittsburgh record moguls, to make a novelty record.  Bob and the two record men assembled "Convention '72," a "break-in" record which consisted of Bob "imitating" several popular television reporters of the day, including Walter Cronkite ("Walter Klondike"), Chet Huntley ("Sidney Bruntley" as a flamboyantly gay reporter - for some reason), David Brinkley ("David Stinkley"), and Harry Reasoner ("Larry Reasoning") asking questions of current politicians involved in that year's presidential election (such as Thomas Eagleton, Sargent Shriver, Spiro Agnew, Richard Nixon, Edward Kennedy, George McGovern, Martha Mitchell, Jane Fonda and Henry Kissinger) at a joint national "Get Together" convention of Republicans and Democrats, with the responses given as lines from popular songs of the day (in a manner analogous to that made famous by Dickie Goodman).

He became National Security Advisor in 1969 and later concurrently United States Secretary of State in 1973.  For his actions negotiating a ceasefire in Vietnam, Kissinger received the 1973 Nobel Peace Prize under controversial circumstances, with two members of the committee resigning in protest.  Kissinger later sought, unsuccessfully, to return the prize after the ceasefire failed.

Richard Nixon: Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th President of the United States from 1969 until 1974, when he resigned from office, the only U.S. president to do so.

Case–Church Amendment: The Case–Church Amendment was legislation approved by the U.S. Congress in June 1973 that prohibited further U.S. military activity in Vietnam, Laos and Cambodia unless the president secured Congressional approval in advance.  This ended direct U.S. military involvement in the Vietnam War, although the U.S. continued to provide military equipment and economic support to the South Vietnamese government.  It is named for its principal co-sponsors, Senators Clifford P. Case (R-NJ) and Frank Church (D-ID).  The Amendment was defeated 48–42 in the U.S. Senate in August 1972, but revived after the 1972 election.  It was reintroduced on January 26, 1973 and approved by the Senate Foreign Relations Committee on May 13.  When it became apparent that the Amendment would pass, President Richard Nixon and Secretary of State Henry Kissinger, lobbied frantically to have the deadline extended.  It passed the United States Congress with bipartisan support in June by a margin of 325–86 in the House, and 73–16 in the Senate.  Both of these margins were greater than the two-thirds majority required to override a presidential veto.  Although U.S. ground forces had been withdrawn earlier under a policy called Vietnamization, bombing continued until August 15, 1973, the deadline set by the Amendment.

Linkage (policy): Linkage was a policy pursued by the United States of America, championed by Richard Nixon and Henry Kissinger, during the 1970s period of Cold War Détente which aimed to persuade the Soviet Union and Communist China to co-operate in restraining revolutions in the Third World in return for concessions in nuclear and economic fields.

Zilch memo: A memorandum known as the Zilch memo was an American government document sent by National Security Advisor Henry Kissinger to President Richard Nixon on January 3, 1972, about the military situation in Laos during the Vietnam War.  On the memo, in his own handwriting, Nixon described the decade-long bombing campaign by the United States in Southeast Asia as a "failure," having achieved "zilch," despite public comments to the contrary.  Just the day before, January 2, Nixon told CBS News reporter Dan Rather in an interview that the bombing was "very, very effective."  Previously missing from the Richard Nixon Library, the memo was discovered in the possession of Alexander Butterfield, who served as the Deputy Assistant to President Nixon from 1969 to 1973, by "Washington Post" reporter Bob Woodward, who subsequently published it in his 2015 book "The Last of the President's Men".
