Question: Which producer who worked on Daylight Crossing is the oldest? Passage:Charley and Hattie collaborated with Jeff Trott (Sheryl Crow, Aimee Mann), Mike Elizondo (Dr. Dre, Fiona Apple), and Steve Booker (Duffy) on material that would become their album Daylight Crossing. Two years later they returned to the UK, where they worked with Universal Records sister company Mercury Records for the album's release. Daylight Crossing was produced by Steve Lipson and Youth, recorded at Sarm Hook End, Abbey Road and Olympic Studios. The album featured musicians Simon Tong and Simon Jones from the band The Verve and Steve Gadd and Pino Palladino. Daylight Crossing was released in June 2006 and became the 'Record of the Week' and 'Album of the Week' at BBC Radio 2, reaching No. 2 on UK's TV music video airplay chart. iTunes chose Daylight Crossing as 'Album of the Week' and singled out the song "Torches" as its 'Single of the Week' during its release week. The Webb Sisters performed on The Sharon Osbourne Show and toured in support of Jamie Cullum (for whom their brother Brad has played drums), Jason Mraz, James Morrison and Kubb, alongside band Leya and Joe Echo. Their song "Still The Only One" was played on the TV show Cane on CBS.

Question: Which player played more games, Al Spalding or Ross Barnes? Passage:The Cincinnati Red Stockings, established in 1869 as the first openly all-professional baseball team, voted to dissolve after the 1870 season. Player-manager Harry Wright, with brother George and two other Cincinnati players, then went to Boston, Massachusetts at the invitation of Boston Red Stockings founder Ivers Whitney Adams to form the nucleus of the Boston Red Stockings, a charter member of the National Association of Professional Base Ball Players (NAPBBP). The original Boston Red Stockings team and its successors can lay claim to being the oldest continuously playing team in American professional sports. (The only other team that has been organized as long, the Chicago Cubs, did not play for the two years following the Great Chicago Fire of 1871.) Two young players hired away from the Forest City club of Rockford, Illinois, turned out to be the biggest stars during the NAPBBP years: pitcher Al Spalding (founder of Spalding sporting goods) and second baseman Ross Barnes.

Question: How long had the European Union been established when Albania was granted membership to NATO? Passage:In 1991, the Socialist Party of Albania, with specific social democratic ideology took control of the country through democratic elections. One year later the Democratic Party of Albania won the new elections. After 1990, Albania has been seeking a closer relationship with the West. What followed were deliberate programs of economic and democratic reform, but Albanian inexperience with capitalism led to the proliferation of pyramid schemes – which were not banned due to the corruption of the government. Chaos in late 1996 to early 1997, as a result of the collapse of these pyramid schemes, alarmed the world and prompted the influx of international peacekeeping forces. In 1995, Albania was accepted into the Council of Europe and requested membership in NATO (obtained in 2009) and is a potential candidate country for accession to the European Union. The workforce of Albania has continued to emigrate to Western countries, especially Greece and Italy.
