Question: How many weeks did the single that peaked at number nine spend on the charts? Passage:"Go Girl" was the first single released from the album. It was originally the lead single from the album, but the single achieved minimum success and was later deemed a promo single. However, the single managed to reach the top of the charts in Japan.

Question: Where was the person who discussed how the king dismissed Warwick born? Passage:Warwick, however, was increasingly discontented with his former protégé, King Edward. Not only did he disagree with the pro-Burgundian and anti-French foreign policy Edward was pursuing, but the king had made an unpopular marriage to Elizabeth Woodville, whom Warwick appears to have considered of parvenu stock. Edward's younger brother George of Clarence was also, for his own reasons, turning against Edward, and by the late 1460s, he and Warwick were in political alliance against the King. In late 1467, Warwick withdrew from the court to the north and his Yorkshire estates. George was equally dissatisfied with his lot under his brother's regime, particularly as Edward had recently forbidden a marriage between George and Warwick's eldest daughter, Isabel Neville. The king had also recently dismissed Warwick and John's brother George from the chancellorship—in (says historian Charles Ross) a "pointed" manner.
