Question: Dolly Parton and Kesha both credit this women as a co-writer on their kit songs.  What is her name?
Context: Writing for "Warrior" began in late 2011 and ended in early 2012, with recording taking place from January through August 2012.  Kesha wrote the majority of the album while touring internationally and during her spiritual journey.  Contributions to the album's production came from longtime collaborators Dr. Luke (who was also the executive producer of the project), Max Martin, Shellback, Ammo and Benny Blanco.  It features guest vocals from American rock singer Iggy Pop, who has been cited as a major influence on the album, as well as writing contributions from Nate Ruess from American indie rock trio Fun, American rapper will.i.am, singer-songwriter Bonnie McKee, The Black Keys drummer Patrick Carney, American rock bands The Strokes and The Flaming Lips and Kesha's own mother, Pebe Sebert.  Upon its release, "Warrior" received generally favorable reviews from music critics, who commended its rock-influenced material, lyrical content, and collaborations whilst others criticized its use of Auto Tune and formulaic content.  The album reached number 6 on the U.S. "Billboard" 200, also charting within Canada, Australia, United Kingdom, Japan and others. "Old Flames (Can't Hold a Candle to You)" is a country song written by singer-songwriter Pebe Sebert and Hugh Moffatt.  It was a number 14 U.S. country hit for Joe Sun in 1978, and a number 86 hit for Brian Collins the same year.  It was later covered by Dolly Parton, who took it to the top of the U.S. country singles charts in August 1980. .  Parton included her version on her 1980 "Dolly, Dolly, Dolly" album, and it was released as the album's second single after the success of "Starting Over Again".  In 2013, Sebert's daughter, Kesha, released an acoustic cover of the song as part of her extended play "Deconstructed".  A new version featuring Parton is on a track of Kesha's 2017 album "Rainbow". Dolly, Dolly, Dolly, released in 1980, is the 22nd solo studio album by Dolly Parton.  Coming at the height of her late 1970s-1980s quest for pop success, the album was her least traditional country-sounding album to that point, with a number of songs bordering on disco.  Though the album's two singles, "Starting Over Again" (written by Donna Summer and Bruce Sudano) and "Old Flames Can't Hold a Candle to You" topped the U.S. country charts ("Starting Over Again" also hit #36 on the pop charts), the album is generally regarded by critics, as well as Parton's fans, as one of the least satisfying albums of her career; it was almost universally panned at the time of its release; of the major press, only "People Magazine" reviewed it favorably.  The album was noteworthy for being one of the only Parton albums to that point not to include a single of her own compositions; it was composed entirely of covers. Just Because I'm a Woman: Songs of Dolly Parton is a various-artists tribute album to Dolly Parton, released on October 14, 2003.  The title song is a rerecording by Parton of a song she originally wrote during the 1960s, and first included on her "Just Because I'm a Woman" album in 1968.  The Emmylou Harris track "To Daddy" was recorded in 1978, and first appeared on Harris' "Quarter Moon in a Ten Cent Town" album (a single release of the song reached #3 on the U.S. country singles chart in early 1978); the remainder of tracks on the albums were new recordings by each of the artists made specifically for this project. Rosemary Patricia "Pebe" Sebert ( ; born March 17, 1956) is an American singer-songwriter from Brentwood, Tennessee, who is the mother of singer-songwriter Kesha.  Pebe is best known for co-writing number-one hits for Dolly Parton, Pitbull and Kesha.  Sebert and Kesha have written 11 released songs together.  The songs Sebert wrote for other artists have combined sales of over 8 million copies in the United States alone.  In 2013, Sebert appeared as a regular on reality show "", which starred Kesha and was filmed by her son Lagan. Dolly Rebecca Parton Dean (born January 19, 1946) is an American singer, songwriter, multi-instrumentalist, record producer, actress, author, businesswoman, and philanthropist, known primarily for her work in country music.  After achieving success as a songwriter for others, Dolly Parton made her album debut in 1967, with her album "Hello, I'm Dolly".  With steady success during the remainder of the 1960s (both as a solo artist and with a series of duet albums with Porter Wagoner), her sales and chart peak came during the 1970s and continuing into the 1980s; Parton's subsequent albums in the later part of the 1990s were lower in sales.  However, in the new millennium, Parton achieved commercial success again and has released albums on independent labels since 2000, including albums on her own label, Dolly Records. "Kentucky Gambler" is a 1974 song written and performed by Dolly Parton.  "Kentucky Gambler" was issued as a track from Dolly Parton's, "The Bargain Store" album from 1975.  That same year, Merle Haggard, covered "Kentucky Gambler" where it was his nineteenth number one song on the country chart.  (Coincidentally, Parton's "The Bargain Store" album featured a cover of a Haggard composition, "You'll Always Be Special to Me".)  The Merle Haggard version stayed at number one for a single week and spent a total of eleven weeks on the chart.  (The following year, Haggard would cover another Dolly Parton song, "The Seeker".) "Please Don't Stop Loving Me" is a song written and recorded as a duet by American country music artists Porter Wagoner and Dolly Parton.  It was released in July 1974 as the first single from the album "Porter 'n' Dolly".  "Please Don't Stop Loving Me" was Porter Wagoner and Dolly Parton's sixteenth country hit and their only number one on the country chart as a duet act.  Though Parton and Wagoner had each topped the charts as solo artists, and many of their duet singles had reached the country top-ten, "Please Don't Stop Loving Me" was their only chart-topper as a duet act.  The single stayed at number one for one week and spent a total of ten weeks on the country chart. Best of Dolly Parton, Vol.3 is a 1987 compilation of Dolly Parton's early- to mid-1980s hits that RCA Records issued after she left the label.  This was the first Dolly Parton CD that featured the song "Potential New Boyfriend". Best of Dolly Parton was a 1975 compilation album of Dolly Parton's early 1970s work that has long been regarded by critics as the definitive representation of Parton's most influential period.  The album reached # 5 on the U.S. country albums chart, and contained the title tracks to the previous six Parton albums, as well as the tracks "I Will Always Love You" and "Travelin' Man".
