Background: The Stone Poneys were a folk-rock trio formed in Los Angeles, consisting of Linda Ronstadt on vocals, Bobby Kimmel on rhythm guitar and vocals, and Kenny Edwards on lead guitar. Their recordings include Ronstadt's first hit song, a cover of Mike Nesmith's "Different Drum". Even at this early stage, Ronstadt was already showcasing her performances of an eclectic mix of songs, often from under-appreciated songwriters, requiring a wide array of backing musicians. As a testament to enduring interest in the trio, the band's three albums: The Stone Poneys; Evergreen, Volume 2; and Linda Ronstadt, Stone Poneys and Friends, Vol. III, were released together as single CDs for the first time in the 1990s in the US (nearly 30 years after the music was recorded), with the first two albums reissued in Australia in 2008.
Context: After the Poneys reformed, Cohen introduced Linda, Kenny, and Bobby to Nick Venet (also known as Nik Venet) at The Troubadour. Venet signed the band to Capitol Records in the summer of 1966. Ronstadt recalls of the signing: "Capitol wanted me as a solo, but Nick convinced them I wasn't ready, that I would develop. It was true." In a late 1966 article in Billboard, Venet discussed the formation of a new record label under Capitol called FolkWorld specifically to promote folk-rock artists. Although the FolkWorld concept was never realized, The Stone Poneys became the lead act in the stable of folk-rock performers that Venet was signing and producing in this time period.  The three albums by The Stone Poneys were produced by Nick Venet. The band's original songs were credited to Bob Kimmel and Kenny Edwards, although subsequent CD reissues removed Edwards' name from most of the credits. BMI's website now credits all original Kimmel-Edwards songs to Kimmel alone, resulting in "Back Home" being Edwards's lone songwriting credit with the Stone Poneys.  The first album, simply called The Stone Poneys was more folk than rock and featured relatively few lead vocals by Ronstadt; it received little notice. The band again broke up briefly between the first two albums; but, as related by Kenny Edwards, Nick Venet told the band: "'We can make another record, we can make this happen. If we're going to do anything with this, we've got to make something that sounds commercial and get on the radio."
Question: Did they have any record deals with anyone else?

Background: 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.
Context: 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).
