Question: Were there any famous performers at the music festival McCollum often performed at? Passage:During the mid-1950s McCollum was highly busy performing as a concert soloist and performed with some frequency in operas with the New England Opera Theatre (NEOT). He sang frequently with the Boston Symphony Orchestra under conductor Charles Munch, often at the Tanglewood Music Festival, performing works like the role of the evangelist in Bach's Johannes Passion (1956). He was also a regular performer with the Dessoff Choirs under conductor Paul Boepple, performing as a tenor soloist in oratorios like Handel's Messiah (1956) and Handel's Israel in Egypt (1957). One work which he performed with frequency during these years was J.S. Bach's Mass in B Minor, which he first performed in February 1955 with the Chicago Symphony Orchestra under conductor Margaret Hillis. He later performed the work with the Boston Symphony Orchestra at Tanglewood in the summer of 1955 and with the Philadelphia Orchestra at the Bethlehem Bach Festival in 1956. In March 1955 he sang Helenus in a lauded production of Berlioz's Les Troyens with the New England Opera Theater opposite Eunice Alberts as Cassandre, Marriquita Moll as Dido, and Arthur Schoep as Aeneas.

Question: Which team that Lepage drove for after he left Ridling raced in NASCAR first? Passage:Lepage made his Busch Series debut in 1986 at Oxford Plains Speedway, starting 41st and finishing 15th in the No. 09 Buick owned by Carl Merrill. He became a Busch Series regular in 1994, serving as an owner/driver in the No. 71 Vermont Teddy Bear Company car and running for Rookie of the Year honors. He had a best finish of 9th at New Hampshire International Speedway, in which he got a flat tire at the very end of the race, and finished 24th in points. The 1995 season resulted in five Top 10s and finishing 18th in points. At the end of the season, he lost his sponsorship and ran his own car in 1996 unsponsored until April. Lepage then joined David Ridling and his No. 88 Ridling Motorsports team with sponsorship from Ridling's own Farmer's Choice Fertilizer. He won his first career race at the season finale Jiffy Lube Miami 300 with Hype Energy sponsorship. He finished eighth in points with 1 win, three Top 5s and 10 Top 10s. He ran most of the 1997 season driving for Ridling before leaving due to the team losing its sponsor. Lepage would finish out the year running for Phoenix Racing and ST Motorsports. He finished 12th in points, posting three Top 5s and six Top 10s. Lepage had his Cup debut by qualifying for the Fall Charlotte race in the No. 91 LJ Racing car in an impressive 12th. He would also run the Fall Talladega and Atlanta races with finishes of 17th at Talladega and 29th at Atlanta.

Question: How many total London clubs have played in the UEFA Champions League? Passage:Football is now the most popular spectator sport in London, and the city has several of England's leading clubs. Most London clubs are named after the district in which they play (or used to play). Historically the London clubs have not accumulated as many trophies as those from the north-west of England, such as Liverpool and Manchester United, but at present Arsenal (founded at Woolwich Arsenal but playing in Holloway), and Chelsea (who actually play in Fulham) are regarded as two of the Premier League's "big four" alongside Manchester United and Liverpool. In 2003–04 they became the first pair of London clubs to finish first and second in the top flight, with Arsenal winning. In 2004–05 they did so again, this time with Chelsea winning. In 2009–10, three of the top four places were occupied by London sides—Chelsea (champions), Arsenal (3rd) and Tottenham Hotspur (4th). This meant that the 2010–11 season would see three London clubs in the UEFA Champions League for the first time ever.
