Problem: Background: Stephen Roche (; born 28 November 1959) is an Irish former professional road racing cyclist. In a 13-year professional career, he peaked in 1987, becoming the second of only two cyclists to win the Triple Crown of victories in the Tour de France and the Giro d'Italia stage races, plus the World road race championship, the first was Eddy Merckx. Roche's rise coincided with that of fellow Irishman Sean Kelly. Although one of the finest cyclists of his generation and admired for his pedalling style, he struggled with knee injuries and never contended in the Grand Tours post-1987.
Context: At the close of 1987, Roche moved to Fagor MBK, bringing English riders Sean Yates and Malcolm Elliot, 1984 Tour de France King of the Mountains winner Robert Millar and domestique Eddy Schepers. The team was criticised for containing too many English speakers. The 1988 season began badly with a recurrence of the knee injury and Roche began a gradual decline. In 1989 he again took second in Paris-Nice (making four second places) and the Setmana Catalana de Ciclisme. Roche finished the 1989 Giro d'Italia ninth behind Laurent Fignon. During the 1989 Tour de France, Roche withdrew due to his knee. There were problems with his team in and he changed again. In 1990, racing for Histor Sigma, he won the Four Days of Dunkirk and 1991 riding for Roger De Vlaeminck's TonTon Tapis brought victories in the Setmana Catalana de Ciclisme and Criterium International. In the 1991 Tour de France, Roche missed the start for his team's Team time trial and was forced to withdraw due to controversially missing the time cut. In the Grand Tours, he was ninth in the 1989 Giro, and won a stage of the 1992 Tour de France in appalling conditions into La Bourboule (again racing for Carrera Jeans-Vagabond but now in support of Claudio Chiappucci) and en route to a final ninth place. Riding the last edition of the Nissan Classic Tour of Ireland, Roche was in many breaks but finished fifth. A year later, he was again ninth in the 1993 Giro d'Italia and 13th in the 1993 Tour de France. Roche retired at the end of an anonymous 1993 which yielded a single win, in the post-Tour de France criterium at Chateau Chinon.
Question: did he change his career post 1987
Answer:

Problem: Background: Nehemiah Curtis "Skip" James (June 9, 1902 - October 3, 1969) was an American Delta blues singer, guitarist, pianist and songwriter. His guitar playing is noted for its dark, minor-key sound, played in an open D-minor tuning with an intricate fingerpicking technique. James first recorded for Paramount Records in 1931, but these recordings sold poorly, having been released during the Great Depression, and he drifted into obscurity. After a long absence from the public eye, James was "rediscovered" in 1964 by blues enthusiasts, helping further the blues and folk music revival of the 1950s and early 1960s.
Context: For the next thirty years, James recorded nothing and performed sporadically. He was virtually unknown to listeners until about 1960. In 1964, blues enthusiasts John Fahey, Bill Barth, and Henry Vestine found him in a hospital in Tunica, Mississippi. According to Calt, the "rediscovery" of both James and Son House at virtually the same time was the start of the blues revival in the United States. In July 1964 James and other rediscovered musicians appeared at the Newport Folk Festival. Several photographs by the blues promoter Dick Waterman captured this performance, James's first in over 30 years. After that James recorded for Takoma Records, Melodeon Records, and Vanguard Records and performed at various engagements until his death in 1969. More of James's recordings have been available since his death than were available during his lifetime. His 1931 recordings and several of his recordings and concerts from the 1960s have been reissued on numerous compact discs, in and out of print. His songs were not initially recorded as frequently as those of other rediscovered blues musicians. However, the British rock band Cream recorded "I'm So Glad", providing James with the only windfall of his career. Subsequently, Cream's adaptation was recorded by other groups. James' "22-20" inspired for the name for the English group 22-20s and the British post-rock band Hope of the States released a song partially about the life of James, entitled "Nehemiah", which reached number 30 on the UK Singles Chart. In 2004, Wim Wenders directed the film The Soul of a Man (the second part of The Blues, a series produced by Martin Scorsese), focusing on the music of Blind Willie Johnson, J.B. Lenoir and James. Because James had not been not filmed before the 1960s, Keith B. Brown played the part of the young James in the documentary.
