Question:
Giacomo Costa (14 December 1919 - 22 January 2000) was an Italian Australian professional wrestler best known by his ring name, Al Costello. Costello was the first professional wrestler to be nicknamed "The Man of a Thousand Holds" because of his innovative and very technical style. Costello was the creator and original member of the tag team The Fabulous Kangaroos, whose "Ultra Australian" gimmick complete with boomerangs, bush hats and the song "Waltzing Matilda" as their entrance music, existed in various forms from 1957 until 1983. Costello was either an active wrestler, or a manager in all versions of The Fabulous Kangaroos.
Heffernan returned to Australia and began working for World Championship Wrestling (the Australian version, not the North American wrestling federation) under booker Jim Barnett as a singles wrestler. Costello was originally supposed to return to Australia as well and work for WCW, but those plans never came through. Instead, Costello remained in the United States and kept working in the tag team division, never seeking a career as a singles wrestler. Costello began wrestling for Georgia Championship Wrestling, where he teamed up with Louis Tillet to form a tag team known as "The Globetrotters"; a name that played off Costello's Australian and Tillet's French heritage. The Globetrotters defeated the Mysterious Medics in the finals of the Georgia NWA World Tag Team Championship but only held the titles for a week before losing them to Kurt and Karl Von Brauner on 4 February 1966. After this, the Globetrotters broke up due to differences in their approach to tag teaming. Costello then moved to the NWA Mid-America territory near Nashville, Tennessee. In Mid-American, Costello teamed with Herb Welch to win the Mid-American version of the NWA World Tag Team Championship, which they held for just over 2 months. While still working in Mid-America, Costello began to team with Karl Von Brauner, who used a "German Nazi" gimmick despite being American. Under the management of "Playboy" Gary Hart, Costello and Von Brauner were billed as "The Internationals"; the team was later managed by George "Crybaby" Cannon. The Internationals worked mainly in Tennessee and Texas for NWA Western States. In Texas, Costello and Von Brauner won the Texas version of the NWA World Tag Team Championship, a title Costello and Heffernan had held in 1958. The team was also billed as the first NWA American Tag Team Champions, titles that were also recognized by World Class Championship Wrestling in addition to the Western States promotion. The Internationals lost the American Tag Team title to Fritz and Waldo Von Erich on 21 February 1967. Kurt then decided to go back to teaming with his storyline brother, Karl Von Brauner. After the Internationals broke up, Costello returned to Australia to visit friends and relatives and to recuperate after many years on the road. On his way back to the United States, Costello had a stop over in Detroit, Michigan, where he met Cleo Williams. The two fell in love and married shortly afterwards, remaining together for the rest of Costello's life.

input: Simon's characters are typically portrayed as "imperfect, unheroic figures who are at heart decent human beings", according to Koprince, and she traces Simon's style of comedy to that of Menander, a playwright of ancient Greece. Menander, like Simon, also used average people in domestic life settings, the stories also blending humor and tragedy into his themes. Many of Simon's most memorable plays are built around two-character scenes, as in segments of California Suite and Plaza Suite. Before writing, Simon tries to create an image of his characters. He says that the play, Star Spangled Girl which was a box-office failure, was "the only play I ever wrote where I did not have a clear visual image of the characters in my mind as I sat down at the typewriter." Simon considers "character building" as an obligation, stating that the "trick is to do it skillfully". While other writers have created vivid characters, they have not created nearly as many as Simon: "Simon has no peers among contemporary comedy playwrights," states biographer Robert Johnson. Simon's characters often amuse the audience with sparkling "zingers," believable due to Simon's skill with writing dialogue. He reproduces speech so "adroitly" that his characters are usually plausible and easy for audiences to identify with and laugh at. His characters may also express "serious and continuing concerns of mankind ... rather than purely topical material". McGovern notes that his characters are always impatient "with phoniness, with shallowness, with amorality", adding that they sometimes express "implicit and explicit criticism of modern urban life with its stress, its vacuity, and its materialism." However, Simon's characters will never be seen thumbing his or her nose at society."

Answer this question "Did his characters change as he matured?"
output: His characters may also express "serious and continuing concerns of mankind ... rather than purely topical material".

Answer the question at the end by quoting:

Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist/bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt.
Following the success of Hell Awaits, Slayer was offered a recording contract with Russell Simmons and Rick Rubin's newly founded Def Jam Records, a largely hip hop-based label. The band accepted and with an experienced producer and major label recording budget, the band underwent a sonic makeover for their third album Reign in Blood resulting in shorter, faster songs with clearer production. Gone were the complex arrangements and long songs featured on Hell Awaits, ditched in favor of stripped down, hardcore punk influenced song structures. Def Jam's distributor, Columbia Records, refused to release the album due to the song "Angel of Death" which detailed Holocaust concentration camps and the human experiments conducted by Nazi physician Josef Mengele. The album was distributed by Geffen Records on October 7, 1986. However, due to the controversy, Reign in Blood did not appear on Geffen Records' release schedule. Although the album received virtually no radio airplay, it became the band's first to enter the Billboard 200, debuting at number 94, and the band's first album certified gold in the United States. In October 1986, Slayer embarked on the Reign in Pain world tour, with Overkill in the US, and Malice in Europe. The band was added as the opening act on W.A.S.P.'s US tour, but just one month in, drummer Lombardo left the band: "I wasn't making any money. I figured if we were gonna be doing this professionally, on a major label, I wanted my rent and utilities paid." To continue with the tour, Slayer enlisted Tony Scaglione of Whiplash. However, Lombardo was convinced by his wife to return in 1987. At the insistence of Rubin, Slayer recorded a cover version of Iron Butterfly's "In-A-Gadda-Da-Vida" for the film Less Than Zero. Although the band was not happy with the final product, Hanneman deeming it "a poor representation of Slayer" and King labeling it "a hunk of shit," it was one of their first songs to garner radio airplay.
