Problem: Background: You Bet Your Life is an American comedy quiz series that aired on both radio and television. The original and best-known version was hosted by Groucho Marx of the Marx Brothers, with announcer and assistant George Fenneman. The show debuted on ABC Radio on October 27, 1947, then moved to CBS Radio debuting October 5, 1949, before making the transition to NBC-TV and NBC Radio on October 4, 1950. Because of its simple format, it was possible to broadcast the show simultaneously on radio and television.
Context: The mid-1940s was a lull in Groucho Marx's career. His radio show Blue Ribbon Town, sponsored by Pabst Blue Ribbon beer, had begun in March 1943 and had failed to catch on. Groucho left the program in June 1944, replaced by vocalist Kenny Baker until the show's end two months later. He also reluctantly appeared in two movies with brothers Chico and Harpo Marx, A Night in Casablanca and the lackluster Love Happy.  During a radio appearance with Bob Hope in March 1947, Marx ad-libbed most of his performance after being forced to stand by in a waiting room for 40 minutes before going live on the air. John Guedel, the Hope program's producer, formed an idea for a quiz show and approached Marx about the subject.  After initial reluctance by Marx, Guedel was able to convince him to host the program once Marx realized the quiz would be only a backdrop for his contestant interviews and the storm of ad-libbing that they would elicit. Guedel also convinced Marx to invest in 50% of the show, in part by saying that he was "untouchable" at ad-libbing, but not at following a script.  As Marx and the contestants were ad-libbing, he insisted that each show be filmed and edited before release to remove the risque or less interesting material. The show for the studio audience ran longer than the broadcast version. The president of Film Craft Productions, which did the filming, cited it as the first television show filmed before a live audience as part of a lengthy essay about production procedures.

Problem: Background: Electric Ladyland is the third and final studio album by English-American rock band the Jimi Hendrix Experience, released in October 1968 by Track Records/Polydor, and Reprise Records in North America. The double album was the only record from the band produced by Jimi Hendrix. By mid-November, it had charted at number one in the United States, where it spent two weeks at the top spot. Electric Ladyland was the Experience's most commercially successful release and their only number one album.
Context: According to music journalist David Stubbs, Electric Ladyland is "undoubtedly a rock album, albeit rock on the point of evolving into something else." Uncut magazine's John Robinson said that its music reconciles the psychedelic pop of Hendrix's earlier recordings with the aggressive funk he would explore on his 1970 album Band of Gypsys. During its recording, Kramer experimented with innovative studio techniques such as backmasking, chorus effect, echo, and flanging, which AllMusic's Cub Koda said recontextualized Hendrix's psychedelic and funk sounds on the album.  Electric Ladyland is a cross-section of Hendrix's wide range of musical talent. It includes examples of several genres and styles of music: the psychedelic "Burning of the Midnight Lamp", a UK single the previous summer (1967), the extended blues jam "Voodoo Chile", the New Orleans-style R&B of Earl King's "Come On", the epic studio production of "1983... (A Merman I Should Turn to Be)", the social commentary of "House Burning Down", and the Sixties-era Britpop of Noel Redding's "Little Miss Strange". The album also features an electric reworking of the Bob Dylan classic "All Along the Watchtower", which has been well received by critics as well as by Dylan himself, and also "Voodoo Child (Slight Return)", a staple of both radio and guitar repertoire. Rolling Stone's Holly George-Warren praised "Crosstown Traffic" for its hard rock guitar riff.  "All Along the Watchtower" became the band's highest-selling single and their only US top 40 hit, peaking at number 20; it reached number five in the UK. The album also included one of Hendrix's most prominent uses of a wah-wah pedal, on "Burning of the Midnight Lamp", which reached number 18 in the UK charts.
Question: what other singles?
Answer: All Along the Watchtower", which has been well received by critics as well as by Dylan himself, and also "Voodoo Child (Slight Return)",

Problem: Background: Richard John Grayson is a fictional character, a superhero appearing in American comic books published by DC Comics, commonly in association with Batman. Created by writer Bill Finger and artist Bob Kane, he first appeared in Detective Comics #38 in April 1940 as the original incarnation of Robin. In Tales of the Teen Titans #44 (July 1984) the character retires his role as Robin and assumes the superhero persona of Nightwing, created by Marv Wolfman and artist George Perez. The youngest in a family of Gotham City acrobats known as the "Flying Graysons", Dick watches a mafia boss kill his parents in order to extort money from the circus that employed them.
Context: 1964's The Brave and the Bold #54 introduces a junior version of the Justice League of America; an all-star superhero team of which Batman was a part. This team is led by the modern-day Robin, residing on Earth-One, and was joined by two other teenage sidekicks, Aqualad (sidekick of Aquaman) and Kid Flash (sidekick of the Flash), to stop the menace of Mr. Twister.  Later, the three sidekicks join forces with Speedy and Wonder Girl in order to free their mentors in the JLA from mind-controlled thrall. They decide to become a real team: the Teen Titans. By virtue of the tactical skills gleaned from Batman, Robin is swiftly recognized as leader before the Titans disband some years later.  In 1969, still in the Pre-Crisis continuity, writer Dennis O'Neil and artist Neal Adams return Batman to his darker roots. One part of this effort is writing Robin out of the series by sending Dick Grayson to Hudson University and into a separate strip in the back of Detective Comics. The by-now Teen Wonder appears only sporadically in Batman stories of the 1970s as well as a short lived revival of The Teen Titans.  In 1980, Grayson once again takes up the role of leader of the Teen Titans, now featured in the monthly series The New Teen Titans, which became one of DC Comics's most beloved series of the era. During his leadership of the Titans, however, he had a falling out with Batman, leading to an estrangement that would last for many years.
Question: What role did he play in Teen Titans?

In 1980, Grayson once again takes up the role of leader of the Teen Titans,
