Question: How old was Bob Dylan the year George Harrison was in Los Angeles? Passage 1:In early April 1988, George Harrison was in Los Angeles and needed to record a B-side for a European 12-inch single. Jeff Lynne was also in Los Angeles writing and producing some tracks for Roy Orbison on his album Mystery Girl (released posthumously), as well as Tom Petty’s first solo album, Full Moon Fever. While having dinner with Lynne and Orbison, Harrison related how he needed to record a new track and wanted to do it the next day. Harrison asked if Lynne would help, and Orbison offered his old friend his hand as well, seeing how fun it would be. Needing a studio at short notice, Harrison called Bob Dylan, who agreed to let them use his garage studio. After dinner, Harrison stopped by Petty’s house to pick up a guitar he had left there, and invited Petty along too. Gathering at Dylan’s Malibu home the following day, Harrison, Lynne, Orbison and Petty worked on a song that Harrison had started writing for the occasion, "Handle with Care". At first, Dylan's role was that of a host, maintaining a barbecue to feed the musicians; at Harrison's invitation, Dylan then joined them in writing lyrics for the song. The ensemble taped the track on Dylan's Ampex recording equipment, with all five sharing the vocals.
 Passage 2:At the start of the 1922 season, Kopf was a member of the Giants second team, which was compiled of players who were cut from New York's spring training roster and assigned to a team that played minor league teams in Texas. After his trial with the Giants second team, he was assigned to the Double-A Newark Bears of the International League. After a week with the Bears, Kopf was turned back to the Giants and manager John McGraw gave him an unconditional release. Later that year, he signed with the Brooklyn Dodgers. The Dodgers assigned Kopf to the Double-A Oakland Oaks of the Pacific Coast League. With the Oaks, he batted .246 with 16 hits, and five doubles in 20 games played. Brooklyn then assigned him to Newark Bears. Finally, the Dodgers sold Kopf to the Double-A Reading Aces of the International League. His combined totals in the International League that season was a batting average of .228 with 18 hits, three doubles, and two home runs in 23 games played.
 Passage 3:He was an ensemble member of Theater Basel from 1955 to 1957. He was then a member of the Städtische Bühnen Oberhausen (1958–1959), Stadttheater Gießen (1959–1960), Opernhaus Kiel (1960–1962) and the Staatstheater Kassel (1962–1965). In Kassel, he appeared as Ceccho in the world premiere of the complete version of Henze's König Hirsch on 10 March 1963, and as the Father in Ján Cikker's Abend, Nacht und Morgen on 5 October 1963. He sang at the Opernhaus Dortmund from 1965 to 1968, where he appeared as Valzacchi in Der Rosenkavalier by Richard Strauss in the opening performance of the new opera house on 3 March 1966. Other roles there included the Narrator in Orff's Der Mond, Goro in Puccini's Madama Butterfly, the Knusperhexe in Humperdinck's Hänsel und Gretel, Wenzel in Smetana's Die verkaufte Braut and Wolfgang Capito in Hindemith's Mathis der Maler. He took part in the premiere of Eli by Walter Steffens in 1967.
