Q: Question: How many albums total did the Beatles record in Hamburg? Passage 1:Ain't She Sweet was an American album featuring four tracks recorded in Hamburg in 1961 by The Beatles featuring Tony Sheridan (except for the title song with vocal by John Lennon) and cover versions of Beatles and British Invasion-era songs recorded by the Swallows. As Atlantic Records only had rights to four Sheridan/Beatle recordings recorded by Polydor Records, they filled the rest of the album with Beatle and British Invasion cover songs. When this material was released by Atco Records, there were mono (catalogue number 33-169) and stereo (SD 33-169) editions. Atco also added additional drum overdubs to the four Sheridan cuts on top of the original drum tracks. American drummer Bernard Purdie claims to have performed overdubs of unspecified Beatles records, which would most likely have been for Ain't She Sweet, but this has never been officially confirmed.
 Passage 2:The river starts at Ralph Bice Lake (formerly Butt Lake) in northern Algonquin Provincial Park in the geographic township of Butt in the Unorganized South Part of Nipissing District. It flows south to Daisy Lake then east to Big Trout Lake. The river heads north out the lake over Big Trout Lake Dam, takes in the left tributary Tim River, flows over the Portal Rapids, Cedar Rapids, Snowshoe Rapids, Catfish Rapids, and Stacks Rapids to reach Cedar Lake, the location of the community of Brent, where it takes in the left tributary Nipissing River. The river exits the lake over a dam, heads through the Devil's Chute, reaches Radiant Lake, where it takes in the left tributary North River and right tributary Little Madawaska River, and passes through the Squirrel Rapids, Big Sawyer Rapids, Battery Rapids Cascade Rapids and White Horse Rapids, and takes in the right tributary Crow River. The river then continues through a series of rapids including the Devil's Cellar Rapids, passes the Algonquin Radio Observatory, and reaches Lake Travers. The Petawawa River enters a canyon and passes through numerous rapids including the Big Thompson Rapids, Little Thompson Rapids, Grillade Rapids, Crooked Chute, Rollway Rapids, The Natch, Schooner Rapids, Five Mile Rapids to arrive at Whitson Lake adjacent to the Petawawa Hills. It leaves Algonquin Provincial Park and enters the municipality of Laurentian Hills in Renfrew County, continues southeast past CFB Petawawa, passes through the Crooked Rapids, Race Horse Rapids, White Horse Rapids and Halfmile Rapids, and reaches Lac du Bois Dur, where it takes in the right tributary Barron River. The river enters the town of Petawawa, heads under Ontario Highway 17, through the Big Eddy Rapids, under the Canadian Pacific Railway main line, and empties into Black Bay on the Ottawa River.
 Passage 3:Sobel was born in Brooklyn, New York, and attended Brooklyn College, graduating with a degree in history in 1967. She then attended the City University of New York, where she received a master's degree in social studies education in 1968, and Columbia University, receiving a master's degree in learning disabilities in 1975. In 1976, Sobel moved to Florida, where she worked as a school teacher and a community activist, working on the campaigns of mayoral candidate Mara Giulanti and City Commission candidate Kenneth A. Gottlieb, who would later go on to serve in the Florida House of Representatives with Sobel. When Suzanne Gunzburger resigned from the Hollywood City Commission following her election to the Broward County Commission, Sobel's unique approach through more than 1,000 signatures supporting her appointment was a first time approach to an open appointed seat and was elected by the City Commission to replace Gunzburger on November 20, 1992. Sobel served as Vice Mayor of Hollywood from 1996-1997. Until 1998, she served on the City Commission when she was narrowly defeated for re-election by former Mayor Sal Oliveri by just 139 votes. In light of her defeat, she remarked, "I look out there and I see people who have worked together, a city that has moved forward in four years. We tried our best. These things happen."
