Problem: Edgar Yipsel "Yip" Harburg (born Isidore Hochberg, Yiddish: ysydvr hvkbrg; April 8, 1896 - March 5, 1981) was an American popular song lyricist who worked with many well-known composers. He wrote the lyrics to the standards "Brother, Can You Spare a Dime?"

Harburg and Gorney were offered a contract with Paramount: in Hollywood, Harburg worked with composers Harold Arlen, Vernon Duke, Jerome Kern, Jule Styne, and Burton Lane, and later wrote the lyrics for The Wizard of Oz, one of the earliest known "integrated musicals," for which he won the Academy Award for Best Music, Original Song for "Over the Rainbow." Of his work on The Wizard of Oz, his son (and biographer) Ernie Harburg has said: So anyhow, Yip also wrote all the dialogue in that time and the setup to the songs and he also wrote the part where they give out the heart, the brains and the nerve, because he was the final script editor. And he--there were eleven screenwriters on that--and he pulled the whole thing together, wrote his own lines and gave the thing a coherence and unity which made it a work of art. But he doesn't get credit for that. He gets lyrics by E. Y. Harburg, you see. But nevertheless, he put his influence on the thing. Working in Hollywood did not stop Harburg's career on Broadway. In the 1940s, he wrote a series of "book" musicals with social messages, including the successful Bloomer Girl (1944), set during the Civil War, which was about temperance and women's rights activist Amelia Bloomer. Harburg's best known Broadway show, Finian's Rainbow (1947) was, in its original production, possibly the first Broadway musical with a racially integrated chorus line, and features his "When the Idle Poor Become the Idle Rich." It was made into a film in 1968 starring Fred Astaire and Petula Clark, directed by Francis Ford Coppola.

What other movies did he work on?

Problem: Steel (John Henry Irons), also known as the Man of Steel, is a fictional character, a superhero in the DC Universe. Introduced in 1993 as one of several replacements for the then-deceased Superman, Steel continued to be an independent superhero after his inspiration's resurrection. He received his own ongoing series which saw him move from Metropolis to Washington, D.C. and join the Justice League of America in Grant Morrison's JLA. He later mentored his niece Natasha who became a superheroine herself.

John Henry Irons is a engineer, and a natural athlete who frequently displays an impressive degree of strength. In addition, he wears a suit of powered armor which grants him flight, enhanced strength, and endurance. Steel modified his suit many times through his career. The initial "Man of Steel" design was armed with a wrist-mounted rivet gun and the sledgehammer (like the one used by his namesake John Henry) that was ubiquitous for most of his designs. The original design on his breastplate featured a metal version of Superman's "S" insignia in tribute to the (temporarily) deceased hero, which Irons removed after the return of Superman. Two later armor designs incorporated a similar, but different, "S" symbol. A large hammer is also a key weapon in the suit's arsenal. His most current "smart hammer" hits harder the farther it is thrown, is capable of independent flight, and has an on-board computer guidance and analysis system capable of detecting a target's stress points. When he wore the Entropy Aegis, he had god-like strength and durability and could enlarge himself to giant size. He also had the ability of flight due to energy wings, could travel through time and space at will, and could fire blasts of energy that would reduce a target to its composite elements. However, the Aegis made him very violent and was slowly erasing his soul. During the 52 event, John Henry Irons was altered by the Everyman Project and had become composed of stainless steel due to Lex Luthor tampering with John's DNA without John's consent. Steel's strength and durability were now on a superhuman level. In addition, he could generate enough heat to turn metal fluid (including his own body, which he can then drip off of himself in small amounts). In 52 Week 29, the metal skin peeled off completely, leaving him, again, a normal human. He has since returned to using powered armor of a design similar to his original "Man of Steel" armor.

What other powers does he have?

Answer with quotes: enhanced strength, and endurance.

Problem: Serebro (Russian: Serebro; English translation: Silver) (Stylized as SEREBRO) is a Russian girl group formed by their manager and producer Maxim Fadeev.

After the decline of their success after "Mama Lover", the group started to record songs for their third studio album. In January 2013, the group announced that they would release their further material in Japan after signing with EMI Music. They also announced that they plan to release a compilation entitled Serebration that includes songs from their first and second studio albums. The group traveled to Japan to promote the compilation album and to do a live concert tour. In March 2013, the group released their promotional single "Sexy Ass", but it failed to chart in Russia. In June 2013, the group released their single "Mi Mi Mi" which charted in Italy, peaking at 5 on the Italian iTunes chart. In July 2013, the group released the song "Malo Tebya". The song was released on Russian radio airplay on 10 July and marked a welcome return to the top ten in Russia for the band, ultimately peaking at number five. A new collaboration with DJ M.E.G., entitled "Ugar" (Ugar), has premiered on the band's Facebook page and the Promo DJ website on 18 September. The group announced that they signed a deal with Republic Records and Universal Music Group and discussed plans to re-release their single "Mi Mi Mi" as their first international single. On 28 September, member Anastasia Karpova confirmed her planned departure from the group. Karpova had told Fadeev months prior that she intended to leave the group. She noted that the decision was mutual with other members of the band and that her primary motivation was to pursue a solo career. A new member, named Dasha Shashina, was announced on 3 October 2013. Shashina had re-recorded Anastasia's recordings in the group's songs "Malo Tebya" and "Ugar", which is expected to release a video with Shashina featuring in it. Temnikova left the group in May 2014, ahead of her planned December exit, after having become pregnant. Karpova temporarily returned until newest member Polina Favorskaya was introduced on June 5, 2014. Serebro's 3rd studio album '925' was supposed to be released on iTunes Russia on 15 October 2015 but due to their studio harddrive being stolen, the album release had to be cancelled.
