Q: Question: Who were the other members of the band that Patrick and Bill both left? Passage:Flags is a 1985 album by the duo Moraz-Bruford. Unlike their prior effort Music for Piano and Drums, which featured only an acoustic drum kit and grand piano, this recording expanded their musical palette by including a Kurzweil 250 synthesizer and electronic percussion. Keyboardist Patrick Moraz and drummer Bill Bruford had both previously been members of the progressive rock band Yes (though at different points in time) and also appeared together on Chris Squire's first solo album Fish Out of Water. During the recording of this album, Moraz was a member of The Moody Blues, while Bruford's band King Crimson had just begun a hiatus that would last for ten years. Flags features ten instrumental works, including a drum solo based on Max Roach's "The Drum Also Waltzes".

Q: Question: How many years after they got married did Henry IV become King of England? Passage:The widespread use of the swan as a badge largely derives from the legend of the Swan Knight, today most familiar from Richard Wagner's opera Lohengrin. A group of Old French chansons de geste called the Crusade cycle had associated the legend with the ancestors of Godfrey of Bouillon (d. 1100), the hero of the First Crusade. Although Godfrey had no legitimate issue, his family had many descendants among the aristocracy of Europe, many of whom made use of the swan in their heraldry or as a para-heraldic emblem. In England these included the important de Bohun family, which used the so-called Bohun swan as its heraldic badge; after the marriage in 1380 of Mary de Bohun (d. 1394) to the future King Henry IV of England, the swan became adopted by the House of Lancaster, who continued to use it for over a century. The swan with the crown and chain is especially associated with Lancastrian use; it echoes the crown and chain of Richard II's white hart, which he began to use as a livery badge from 1390. As well as several of his own white hart badges, Richard's treasure roll of 1397 also includes a swan badge with a gold chain, perhaps presented by one of his enemies mentioned above: "Item, a gold swan enamelled white with a little gold chain hanging around the neck, weighing 2 oz., value, 46s. 8d". He declared to Parliament that he had exchanged liveries with his uncles as a sign of amity at various moments of reconciliation.
