Answer the question at the end by quoting:

David Michael Letterman (born April 12, 1947) is an American television host, comedian, writer, and producer. He hosted a late night television talk show for 33 years, beginning with the February 1, 1982, debut of Late Night with David Letterman on NBC, and ending with the May 20, 2015, broadcast of Late Show with David Letterman on CBS. In total, Letterman hosted 6,028 episodes of Late Night and Late Show, surpassing friend and mentor Johnny Carson as the longest-serving late night talk show host in American television history. In 1996 Letterman was ranked 45th on TV Guide's 50 Greatest TV Stars of All Time.
NBC kept Letterman under contract to try him in a different time slot. Late Night with David Letterman debuted February 1, 1982; the first guest on the first show was Bill Murray. Murray later went on to become one of Letterman's most recurrent guests, guesting on the show's 30th anniversary episode, which aired January 31, 2012 and on the very last show, which aired May 20, 2015. The show ran Monday through Thursday at 12:30 a.m. Eastern Time, immediately following The Tonight Show Starring Johnny Carson (a Friday night broadcast was added in June 1987). It was seen as being edgy and unpredictable, and soon developed a cult following (particularly among college students). Letterman's reputation as an acerbic interviewer was borne out in verbal sparring matches with Cher (who even called him an asshole on the show), Shirley MacLaine, Charles Grodin, and Madonna. The show also featured comedy segments and running characters, in a style heavily influenced by the 1950s and 1960s programs of Steve Allen.  The show often featured quirky, genre-mocking regular features, including "Stupid Pet Tricks" (which had its origins on Letterman's morning show), Stupid Human Tricks, dropping various objects off the roof of a five-story building, demonstrations of unorthodox clothing (such as suits made of Alka-Seltzer, Velcro and suet), a recurring Top 10 list, the Monkey-Cam (and the Audience Cam), a facetious letter-answering segment, several "Film[s] by My Dog Bob" in which a camera was mounted on Letterman's own dog (often with comic results) and Small Town News, all of which would eventually move with Letterman to CBS.  Other memorable moments included Letterman using a bullhorn to interrupt a live interview on The Today Show, announcing that he was the NBC News president and that he was not wearing any pants; walking across the hall to Studio 6B, at the time the news studio for WNBC-TV, and interrupting Al Roker's weather segments during Live at Five; and staging "elevator races", complete with commentary by NBC Sports' Bob Costas. In one infamous appearance, in 1982, Andy Kaufman (who was already wearing a neck brace) appeared with professional wrestler Jerry Lawler, who slapped and knocked the comedian to the ground (though Lawler and Kaufman's friend Bob Zmuda later revealed that the event was staged).

Who were the guests?

the first guest on the first show was Bill Murray.

IN: Pendulum is an Australian drum and bass and electronic rock band founded in 2002. Pendulum originally formed in the city of Perth, Western Australia by Rob Swire, Gareth McGrillen, and Paul "El Hornet" Harding. The band was later expanded to include members, Ben Mount, Peredur ap Gwynedd, and KJ Sawka. Members Swire and McGrillen also formed the electro house duo Knife Party.

Pendulum once again toured Europe in 2009. During this tour they announced that they were working on their third studio album, Immersion. It was announced in December 2009 that Pendulum would be touring for their new album in May 2010. The release date of the album was announced to be sometime "in May" during the live preview party at Matter, and was then announced to be released on 24 May. Pendulum previewed their album Immersion at the Ear Storm night at London's Matter nightclub on Friday 22 January. "Salt in the Wounds", a track from their new album, was Zane Lowe's Hottest Record in the World on BBC Radio 1 on 25 January 2010. On Zane Lowe's show, it was also announced that he wanted to join the band and the first single from the new album would be called "Watercolour". This single also received its first play on Zane Lowe's BBC Radio 1 show on 8 March 2010, and was his Single of the Week for that week. In December 2010, "Watercolour" was found to be featured in the soundtrack of the 2010 hit game "Need for Speed: Hot Pursuit". On 1 April, the music video for "Salt in the Wounds" was released. The video is unique in that it is, according to the band's website, "...the world's first 360deg interactive music video."  "Watercolour" claimed the No.4 spot in the UK Singles Chart, making it their biggest hit to date. On 21 May 2010, the band headlined the annual Radio 1's Big Weekend festival which was held at the Vaynol Estate, Bangor, Gwynedd. The second single from the album, "Witchcraft", was released on 18 July and charted at No.29 in the UK Singles chart, making it their third highest charted single in the UK. The third single from Immersion was "The Island", and just missed the UK Top 40 at No. 41.  Rob Swire had stated that if it had achieved greater success than "Witchcraft", he would have released a song entitled "Ransom", which was taken off Immersion before the album's release. Swire revealed the original files for "Ransom" were corrupted, and that he has no plans to recreate them, therefore it will not be released. However, on 6 April 2011, Pendulum released "Ransom" as a single via their website with all proceeds going to the Help for Japan fund after the tsunami. "Crush" was released as the fourth single in January 2011. In January 2011, Pendulum released a Deluxe Edition of Immersion via iTunes which contained the album's original 15 tracks and a collection of remixes of "Watercolour", "Witchcraft" and "The Island" by other artists including deadmau5, Tiesto and Chuckie. Both the UK and US store were also given the music videos of those three tracks in the release.
