Question: How many sales did What's New make? Passage:In 1983 Linda Ronstadt took a break from recording contemporary music in order to make an album of standards with conductor Nelson Riddle, and their collaboration, What's New went triple Platinum. Barbra Streisand's 1985 release The Broadway Album reached number one and went on to quadruple Platinum certification, so a renewed interest in what came to be known as traditional pop was evident. Mathis had not tried a studio album without current hits or new songs since the ill-fated Broadway project in 1965, so his choice to collaborate with Henry Mancini in 1986 for The Hollywood Musicals, which had a lineup of classics that were mostly from the 1940s, was quite a change of pace. And while he has done some albums of contemporary pop songs since then, the category in which he has received four Grammy nominations since 1992 has been Best Traditional Pop Vocal Album, and the industry has recognized his past work as well. Three of his recordings have been inducted into the Grammy Hall of Fame ("Chances Are" in 1998, "Misty" in 2002, and "It's Not for Me to Say" in 2008), and in 2003 he was given the Grammy Lifetime Achievement Award.

Question: Did Henry VIII or Elizabeth I live longer? Passage:Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban Conservatoire of Music and Dance.

Question: What is the current age of the chairman of the MSG Network who fired Marv Albert? Passage:Marv did his first Knicks game on January 27, 1963 on WCBS Radio. He filled in for his mentor, Marty Glickman, who was away in Europe. The game was against the Celtics at the Boston Garden. For 37 years beginning in 1967, Albert was the voice of the New York Knicks on radio and television (getting his start by being a ball boy for the Knicks before getting his first break on New York radio by sportscaster Marty Glickman) before being let go by James L. Dolan, the chairman of the MSG Network and Cablevision, after Albert criticized the Knicks' poor play on-air in 2004. It was said that Marv's high salary was also a factor. His son Kenny Albert has been a part-time play-by-play announcer for the Knicks since 2009, whenever the older Albert's successor Mike Breen (whom he later followed on the NBA on NBC broadcasts and now works on ESPN and ABC aside from his role at MSG) is unavailable.
