Background: John Griffith "Jack" London (born John Griffith Chaney; January 12, 1876 - November 22, 1916) was an American novelist, journalist, and social activist. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.
Context: London wrote from a socialist viewpoint, which is evident in his novel The Iron Heel. Neither a theorist nor an intellectual socialist, London's socialism grew out of his life experience. As London explained in his essay, "How I Became a Socialist", his views were influenced by his experience with people at the bottom of the social pit. His optimism and individualism faded, and he vowed never to do more hard physical work than necessary. He wrote that his individualism was hammered out of him, and he was politically reborn. He often closed his letters "Yours for the Revolution."  London joined the Socialist Labor Party in April 1896. In the same year, the San Francisco Chronicle published a story about the twenty-year-old London giving nightly speeches in Oakland's City Hall Park, an activity he was arrested for a year later. In 1901, he left the Socialist Labor Party and joined the new Socialist Party of America. He ran unsuccessfully as the high-profile Socialist candidate for mayor of Oakland in 1901 (receiving 245 votes) and 1905 (improving to 981 votes), toured the country lecturing on socialism in 1906, and published two collections of essays about socialism: The War of the Classes (1905) and Revolution, and other Essays (1906).  Stasz notes that "London regarded the Wobblies as a welcome addition to the Socialist cause, although he never joined them in going so far as to recommend sabotage." Stasz mentions a personal meeting between London and Big Bill Haywood in 1912.  In his late (1913) book The Cruise of the Snark, London writes about appeals to him for membership of the Snark's crew from office workers and other "toilers" who longed for escape from the cities, and of being cheated by workmen.  In his Glen Ellen ranch years, London felt some ambivalence toward socialism and complained about the "inefficient Italian labourers" in his employ. In 1916, he resigned from the Glen Ellen chapter of the Socialist Party, but stated emphatically he did so "because of its lack of fire and fight, and its loss of emphasis on the class struggle." In an unflattering portrait of London's ranch days, California cultural historian Kevin Starr refers to this period as "post-socialist" and says "... by 1911 ... London was more bored by the class struggle than he cared to admit."
Question: What happened after he joined the party?
Answer: giving nightly speeches in Oakland's City Hall Park, an activity he was arrested for a year later.

Problem: Background: Les Paul was born Lester William Polsfuss in Waukesha, Wisconsin, to George and Evelyn (Stutz) Polsfuss. His family was of German ancestry. Paul's mother was related to the founders of Milwaukee's Valentin Blatz Brewing Company and the makers of the Stutz automobile. His parents divorced when he was a child.
Context: Paul had hosted a 15-minute radio program, The Les Paul Show, on NBC Radio in 1950, featuring his trio (himself, Ford and rhythm player Eddie Stapleton) and his electronics, recorded from their home and with gentle humor between Paul and Ford bridging musical selections, some of which had already been successful on records, some of which anticipated the couple's recordings, and many of which presented re-interpretations of such jazz and pop selections as "In the Mood", "Little Rock Getaway", "Brazil", and "Tiger Rag". Over ten of these shows survive among old-time radio collectors today.  The show also appeared on television a few years later with the same format, but excluding the trio and retitled The Les Paul & Mary Ford Show (also known as Les Paul & Mary Ford at Home) with "Vaya Con Dios" as the theme song. Sponsored by Warner-Lambert's Listerine mouthwash, it was aired on NBC television during 1954-1955, and then syndicated until 1960. The show aired five times a day, five days a week for only five minutes (one or two songs) long, and therefore was used as a brief interlude or fill-in in programming schedules. Since Paul created the entire show himself, including audio and video, he maintained the original recordings and was in the process of restoring them to current quality standards until his death.  During his radio shows, Paul introduced the fictional "Les Paulverizer" device, which multiplies anything fed into it, such as a guitar sound or a voice. It was Paul's way of explaining how his single guitar could be multiplied to become a group of guitars. The device even became the subject of comedy, with Ford multiplying herself and her vacuum cleaner with it so she could finish the housework faster. Later, Paul created a real Les Paulverizer that he attached to his guitar. The invention allowed Paul to access pre-recorded layers of songs during live performances so he could replicate his recorded sound on stage.
