Q: Question: Are both of the band members who put out the album "Flags" still alive? Passage 1:Pyotr Filippovich Berestov (; , Berestovo November 26, 1961, Zaporozhye) was a Red Army major general during the Second World War. Drafted into the Imperial Russian Army in 1917, Berestov participated in the Russian Revolution. He was drafted into the Red Army, fighting in the Russian Civil War and the PolishSoviet War. He became a Red Army officer and served in several positions during the interwar period. Berestov was arrested and released during the Great Purge. He fought in the Winter War as a regimental commander. In the early days after the German invasion of the Soviet Union, he was given command of a People's Militia regiment, which was converted into a regular regiment. Berestov led the regiment in the early period of the Battle of Moscow and transferred to lead a regiment of the 82nd Motor Rifle Division. Berestov became the division's commander and in the spring of 1942 briefly led the 50th Rifle Division. In April, he took command of the 331st Rifle Division, which he led during the rest of the war. For his leadership, Berestov was awarded the title Hero of the Soviet Union in late June 1945. Postwar he commanded the 72nd Guards Rifle Division, which was downsized into a brigade, and the 43rd Guards Rifle Brigade, which became the 113th Guards Rifle Division. Berestov retired in 1955 and lived in Zaporizhia until his death in 1961.
Passage 2:The first known inhabitants of the area now known as Palmer Township were the Lenape Native Americans in the 17th century. German Moravian settlers built on land in the Palmer area in 1740. At the time, the area was part of Bucks County, Pennsylvania, which by the mid-18th century also included land now called Northampton County and Lehigh County. Northampton County separated from Bucks County on March 11, 1752. In 1754, Forks Township, which then also consisted of what is now Palmer Township, was incorporated in 1754 with a total population of about 50 inhabitants. On May 5, 1857, Palmer Township was formed out of the land area of Forks Township south and west of the Bushkill Creek; the original population of the township was about 1,300 people. The township was named after George Palmer, the Pennsylvania Surveyor General who surveyed the original township lines. At the time that it was incorporated, the township was about and included what are now known as the boroughs of Tatamy (which became incorporated in 1893), West Easton (incorporated in 1898), Stockertown (incorporated in 1901) and Wilson (incorporated in 1920). The main activity of Palmer Township during its earliest years was providing access roads from the neighboring city Easton to surrounding communities, including Bethlehem, Freemansburg and Nazareth.
Passage 3: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".
