Question: What regular guest of "7 Day Sunday" also worked extensively with John Oliver on "Political Animal", "The Department", and "The Bugle"?
Context: Political Animal is a performance and radio show created by British comedians John Oliver and Andy Zaltzman in which various stand-up comedians perform political material. 7 Day Sunday "(7 Day Saturday in 2013)" is a British comedy radio talk show hosted by Al Murray on BBC Radio 5 Live.  Broadcast weekly on Sunday mornings, the show takes an irreverent look at the topical news stories of the past seven days.  Originally presented by Chris Addison: he was joined by regular guests Sarah Millican and Andy Zaltzman, and a fourth special guest each episode.  It premièred in January 2010 to mixed reviews.  It returned for a second series in September 2010.  Al Murray served as host for the last five episodes of the second series, joined by regular guests Rebecca Front and Joe Wilkinson.  The show returned for a third series in January 2012 with Al Murray hosting alongside Andy Zaltzman and Rebecca Front as the regular guests.  A fourth series followed from September 2012, with series 5 due to start at 11am on 11 May 2014. Andrew Zaltzman (born 6 October 1974) is a British comedian and author who largely deals in political and sport related material.  He has worked extensively with John Oliver; their work together includes "Political Animal", "The Department", and "The Bugle".  His performance style is centered on verbal dexterity, and on his love (and extensive use) of puns, especially in extended "pun runs" (for example, within "The Bugle" podcast). "Tobacco" is a segment about the tobacco industry, which aired on February 15, 2015, as part of the second episode of the second season of the HBO series "Last Week Tonight with John Oliver".  During the eighteen-minute segment, comedian John Oliver discusses tobacco industry trends and practices.  He also introduces Jeff the Diseased Lung, a mascot he created for the American global cigarette and tobacco company Philip Morris International, the makers of Marlboro cigarettes.  The anthropomorphic diseased lung, who smokes and coughs, has been compared to Joe Camel and the Marlboro Man.  Oliver and his team promoted the cartoon character by sending shirts with Jeff's image to Togo and displaying billboards in Uruguay, and by encouraging use of the hashtag #JeffWeCan, which trended on Twitter following the broadcast. Alex Broun (born 16 March 1965) is an Australian playwright and screenwriter, who has worked extensively with Short+Sweet, a series of theatre festivals for productions of ten minutes or less.  Born in Sydney, Australia, he has been referred to as "the Shakespeare of short plays".  Broun has had over 100 ten-minute plays produced in over 1500 productions in more than 40 countries globally, and his plays have been translated into many languages.  He has also worked extensively as a Rugby journalist and served as Media Manager for the Springboks (1997-2000), the British & Irish Lions (2001) and the Melbourne Rebels (2007). Ronald 'Ronnie' Thomas Verrell (21 February 1926 – 22 February 2002) was an English jazz drummer.  He played in two of the United Kingdom's "most famous" big bands, The Ted Heath Orchestra and The Syd Lawrence Orchestra.  Verrell also worked extensively in television, including as a drummer in Jack Parnell's ATV Orchestra and "Sunday Night at the London Palladium".  He also provided the drumming for "The Muppet Show"' s Animal, and was a "Skinnerette" on "The Frank Skinner Show". Last Week Tonight with John Oliver, often abridged as Last Week Tonight, is an American late-night talk and news satire television program hosted by comedian John Oliver.  The half-hour-long show premiered on Sunday, April 27, 2014, on HBO.  "Last Week Tonight" shares some similarities with Comedy Central's "The Daily Show" (where Oliver was previously featured as a correspondent and fill-in host), as it takes a satirical look at news, politics and current events, but on a weekly basis. "Donald Trump" is a segment of the HBO news satire television series "Last Week Tonight with John Oliver" devoted to Donald Trump, who later became the President of the United States.  It first aired on February 28, 2016, as part of the third episode of "Last Week Tonight"'s third season, when Trump was the frontrunner for the Republican Party nomination for the presidency.  During the 22-minute segment, comedian John Oliver discusses Trump's 2016 presidential campaign and his career in business, outlining his campaign rhetoric, varying political positions and failed business ventures.  He also says the Trump family name was changed at one point from the ancestral name "Drumpf". Earth Day Sunday is a semi-religious holiday that some Christian churches in the United States celebrate on the Sunday before Earth Day.  The day is to raise awareness of the issue of the environment.  Earth Day Sunday is also known as Earth Sunday. The Bugle is a satirical news podcast, created by John Oliver and Andy Zaltzman in 2007.  It was initially produced independently and distributed by TimesOnline until joining the Radiotopia network in September 2016.  Focusing on global news stories (but primarily on UK/US news items), the show was launched in 2007 following John Oliver's move to New York to work on "The Daily Show", allowing Oliver and Andy Zaltzman to continue a partnership that had previously enjoyed success with Political Animal and The Department.  Oliver and Zaltzman co-hosted the podcast from 2007 to 2015, and Zaltman has hosted the podcast with a rotating set of co-hosts since the relaunch in September 2016.
