Question: What was the birthname of the singer-songwriter who was featured in Joan Baez's 1979 album and is known for her album "Between The Lines"?
Context: Janis Ian (born Janis Eddy Fink; April 7, 1951) is an American singer-songwriter who was most commercially successful in the 1960s and 1970s; her most widely recognized song, "At Seventeen", was released as a single from her 1975 album "Between the Lines" which reached number 1 on the Billboard chart. Honest Lullaby is a 1979 album by Joan Baez.  It would be her final album on CBS Records' Portrait imprint, and her last new studio album issued in the U.S. until 1987.  The autobiographical title song was written for her son, Gabriel Harris, and was performed on "The Muppet Show" in 1980.  In addition to her own compositions, the album contained work by Janis Ian and Jackson Browne.  "Let Your Love Flow" was originally a 1976 hit for The Bellamy Brothers.  In her 1987 memoir, "And a Voice to Sing With", Baez speculated that she was likely dropped from CBS due to a political disagreement she'd had with the label's then-president. The Joan Baez Country Music Album is a 1979 compilation album by Joan Baez. Joan Baez is the self-titled debut album by folk singer Joan Baez.  The album was recorded in the summer of 1960 and released the same year.  The original release featured 13 traditional folk songs, later reissues included 3 additional songs. The Contemporary Ballad Book was a 1974 Joan Baez compilation Vanguard put together, following the success of "the Joan Baez Ballad Book".  Unlike the first "Ballad Book", this one focused on singer-songwriter material, rather than traditional folk.  This new compilation contained one previously unreleased track, the Italian song, "C'era un ragazzo che come me amava i Beatles e i Rolling Stones" ('There was this guy who, just like me, loved the Beatles and the Rolling Stones'), taken from Baez' performance at the Isle of Wight Festival. Joan Baez in San Francisco was a demonstration record recorded by the 17-year-old Joan Baez in 1958, released without permission on Fantasy Records in 1964.  Baez sued to block its distribution and it was withdrawn.  There have since been authorized releases on other labels.  It was released by Bear Family Records as A Package of Joan Baez. "Babe I'm Gonna Leave You" is a folk song written by Anne Bredon (then known as Anne Johannsen) in the late 1950s.  It was recorded by Joan Baez (credited and became widely popular as "traditional") and released on her 1962 album "Joan Baez in Concert, Part 1"; and by the English rock band Led Zeppelin, who included it on their 1969 debut album "Led Zeppelin". Gracias a la Vida (subtitled Joan Baez canta en español), or Here's to Life: Joan Baez sings in Spanish is a 1974 studio album released by Joan Baez.  It was performed mainly in the Spanish language (just one song in Catalan language).  Baez stated at the time that she released the album as a "message of hope to the Chileans suffering under Augusto Pinochet", in the wake of the death of Salvador Allende.  (Baez is known for her criticism of US foreign policy in Latin America, and has toured and worked on behalf of improving human rights in the region).  Songs include selections by Chilean composers Victor Jara (who was tortured and killed in the aftermath of the 1973 coup d'état) and Violeta Parra, who composed the title song. The Joan Baez Ballad Book was a 1972 compilation of traditional folk material, culled from Joan Baez' first five Vanguard albums.  Initially issued as a two-record set, the two records were subsequently re-released separately a few years later as "Volume 1" and "Volume 2".  Cover painting was by folk musician and painter Eric Von Schmidt.  Though "Ballad Book" has since been supplanted by the reissue of most of Baez' original Vanguard catalog, for a number of years, it remained the only source to obtain a number of these cuts, as most of her early Vanguard albums temporarily went out of print in the early 1980s. The Joan Baez Lovesong Album was a 1976 compilation Vanguard put together in their series of Joan Baez reissues, following Baez' 1972 departure from their label.  This album was a collection of love songs Baez had recorded during her Vanguard years, including traditional and contemporary work, as well as an arrangement of E. E. Cummings' "All in Green My Love Went Riding" by Peter Schickele.  The cover painting was done by painter and musician Eric Von Schmidt.
