Answer the question at the end by quoting:

Alexandra Elene MacLean Denny (6 January 1947 - 21 April 1978) was an English singer-songwriter who was lead singer of the British folk rock band Fairport Convention. She has been described as "the pre-eminent British folk rock singer". After briefly working with the Strawbs, Denny joined Fairport Convention in 1968, remaining with them until 1969. She formed the short-lived band Fotheringay in 1970, before focusing on a solo career.
Her nursing career proved short-lived. In the meantime she had secured a place on a foundation course at Kingston College of Art, which she took up in September 1965, becoming involved with the folk club on campus. Her contemporaries at the college included guitarist and future member of Pentangle, John Renbourn. After her first public appearance at the Barge in Kingston upon Thames Denny started working the folk club circuit in the evenings with an American-influenced repertoire, including songs by Tom Paxton, together with traditional folk songs. Denny made the first of many appearances for the BBC at Cecil Sharp House on 2 December 1966 on the Folk Song Cellar programme where she accompanied herself on two traditional songs: "Fhir a Bhata" and "Green Grow the Laurels". Her earliest professional recordings were made a few months later in mid-1967 for the Saga label, featuring traditional songs and covers of folk contemporaries including her boyfriend of this period, the American singer-songwriter Jackson C. Frank. They were released on the albums Alex Campbell and His Friends and Sandy and Johnny with Johnny Silvo. These songs were collected on the 1970 album It's Sandy Denny where the tracks from Sandy and Johnny had been re-recorded with more accomplished vocals and guitar playing. The complete Saga studio recordings were issued on the 2005 compilation Where The Time Goes. By this time she had abandoned her studies at art college and was devoting herself full-time to music. While she was performing at The Troubadour folk club, a member of the Strawbs heard her, and in 1967, she was invited to join the band. She recorded one album with them in Denmark which was released belatedly in 1973 credited to Sandy Denny and the Strawbs: All Our Own Work. The album includes an early solo version of her best-known (and widely recorded) composition, "Who Knows Where the Time Goes?" A demo of that song found its way into the hands of American singer Judy Collins, who chose to cover it as the title track of an album of her own, released in November 1968, thus giving Denny international exposure as a songwriter before she had become widely known as a singer.

What did she do there?

Some context: The Riddler (Edward Nigma) is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character made his first appearance in Detective Comics #140 (October, 1948) and was created by Bill Finger and Dick Sprang. Depicted as a Gotham City criminal mastermind, the Riddler takes delight in incorporating riddles and puzzles into his plots, and leaves them as clues for the authorities and Batman to solve. The character is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery.
In Tony Daniel's "Life After Death", Riddler appears early in the story at a gala party attended by Arkham, Dick Grayson, Huntress, and Oracle, hired by Penguin to find the Black Mask. As he chases Catgirl away from her robbery of the venue, the Riddler is rocked by a bomb detonation, the trauma re-awakening his psychosis. Cackling, rambling and insane, he terminates his contract with Cobblepot and disappears. In "Riddle Me This", the Riddler still "acts" as private eye and teams with Batman to solve the murders of a mysterious sorcerer named Sebastian Rothschild (aka Sebastian Blackspell). Blackspell is apprehended, but only after Batman suspects Riddler went to great lengths to orchestrate the ordeal, including poisoning himself with a nearly lethal dose of Joker gas to skirt suspicion and act on a grudge between him and Blackspell. Riddler's return to villainy is cemented in "Eye of the Beholder". Investigating the Sensei's attack on the Jade Society, Batman (Dick Grayson) is ambushed by Riddler and a young woman introduced as Enigma, Riddler's daughter. Riddler and Enigma escape, delivering the Jade Society member list to Gilda Dent. Riddler is paid, but is more interested in another reward, which Gilda promises after one more job. This occurs in "Pieces", where Gilda reveals herself to her estranged husband Harvey, who is now the disfigured criminal Two-Face. She hires Riddler and Enigma to help Two-Face best Mario Falcone and reclaim his coin. The plan works; Riddler and Enigma defeat Batman and reunite the Dents. The Riddler is rewarded with multiple dossiers of himself. When Enigma calls him a has-been, Riddler retorts with a new riddle: "What's green and purple and bleeds profusely?". Enigma's response is cut short by her scream, implying that the Riddler has murdered his own daughter.

IN: Carousel is the second musical by the team of Richard Rodgers (music) and Oscar Hammerstein II (book and lyrics). The 1945 work was adapted from Ferenc Molnar's 1909 play Liliom, transplanting its Budapest setting to the Maine coastline. The story revolves around carousel barker Billy Bigelow, whose romance with millworker Julie Jordan comes at the price of both their jobs. He participates in a robbery to provide for Julie and their unborn child; after it goes tragically wrong, he is given a chance to make things right.

A film version of the musical was made in 1956, starring Gordon MacRae and Shirley Jones. It follows the musical's story fairly closely, although a prologue, set in the Starkeeper's heaven, was added. The film was released only a few months after the release of the film version of Oklahoma!. It garnered some good reviews, and the soundtrack recording was a best seller. As the same stars appeared in both pictures, however, the two films were often compared, generally to the disadvantage of Carousel. Thomas Hischak, in The Rodgers and Hammerstein Encyclopedia, later wondered "if the smaller number of Carousel stage revivals is the product of this often-lumbering [film] musical". There was also an abridged (100 minute) 1967 network television version that starred Robert Goulet, with choreography by Edward Villella. The New York Philharmonic presented a staged concert version of the musical from February 28 to March 2, 2013, at Avery Fisher Hall. Kelli O'Hara played Julie, with Nathan Gunn as Billy, Stephanie Blythe as Nettie, Jessie Mueller as Carrie, Jason Danieley as Enoch, Shuler Hensley as Jigger, John Cullum as the Starkeeper, and Kate Burton as Mrs. Mullin. Tiler Peck danced the role of Louise to choreography by Warren Carlyle. The production was directed by John Rando. Charles Isherwood of The New York Times wrote, "this is as gorgeously sung a production of this sublime 1945 Broadway musical as you are ever likely to hear." It was broadcast as part of the PBS Live from Lincoln Center series, premiering on April 26, 2013.
