Beatles Bop – Hamburg Days is a compilation album of the 1961 recording of Tony Sheridan and The Beatles released by Bear Family Records in 2001. To date, this is the most complete collection of the recordings done with producer Bert Kaempfert for Polydor (excluding the other recordings featured on the My Bonnie/The Beatles' First albums that were done by other musicians under the "The Beat Brothers" name)—featuring both mono and stereo mixes of the album. The album was released in a standard two-CD jewel box with a 99-page booklet as well as a Deluxe Edition packaged in an LP-sized box set which included a 120-page hardcover book which featured rare photos, documents, single picture sleeves and historical notes.

The set has since been deleted from Bear Family's catalogue.

^a The recording of "Swanee River" does not actually feature The Beatles, as tapes of The Beatles version were apparently destroyed in a fire. These non-Beatles versions are included to give an example of what The Beatles version may have sounded like.

Hamburg ( /ˈhæmbɜrɡ/; German pronunciation: [ˈhambʊɐ̯k], local pronunciation [ˈhambʊɪç]; Low German/Low Saxon: Hamborg [ˈhaˑmbɔːx]), officially Free and Hanseatic City of Hamburg, is the second-largest city in Germany, the thirteenth largest German state, and the sixth-largest city in the European Union. The city is home to over 1.8 million people, while the Hamburg Metropolitan Region (including parts of the neighbouring Federal States of Lower Saxony and Schleswig-Holstein) has more than 4.3 million inhabitants. Situated on the river Elbe, the port of Hamburg is the second largest port in Europe (after the Port of Rotterdam) and 11th-largest worldwide.

Hamburg's official name, Free and Hanseatic City of Hamburg (German: Freie und Hansestadt Hamburg), reflects Hamburg's history as a member of the medieval Hanseatic League, as a free imperial city of the Holy Roman Empire, and that Hamburg is a city-state and one of the sixteen States of Germany.

Hamburg is a major transport hub in Northern Germany and is one of the most affluent cities in Europe.  It has become a media and industrial centre, with plants and facilities belonging to Airbus, Blohm + Voss and Aurubis. The radio and television broadcaster Norddeutscher Rundfunk and publishers such as Gruner + Jahr and Spiegel-Verlag are pillars of the important media industry in Hamburg. In total, there are more than 120,000 enterprises.

Tony Sheridan (born Anthony Esmond Sheridan McGinnity on 21 May 1940 in Norwich, Norfolk), is an English rock and roll singer-songwriter and guitarist. He is best known as an early collaborator of The Beatles, (though the record was labelled as being with "The Beat Brothers"), one of two non-Beatles (the other being Billy Preston) to receive label performance credit on a record with the group, and the only non-Beatle to appear as lead singer on a Beatles recording which charted as a single.

In his early life, Sheridan was influenced by his parents' interest in classical music, and by age seven, he had learned to play the violin. He eventually came to play guitar, and in 1956, formed his first band. He showed enough talent that he soon found himself playing in London's "Two I's" club for some six months straight, but at the same time he also found himself reduced to sleeping in doorways. In 1958, at 18, he began appearing on the BBC's Oh Boy, playing electric guitar on such early Rock classics as "Blue Suede Shoes", "Glad All Over", "Mighty Mighty Man" and "Oh Boy!". Sheridan was soon viewed as a very promising guitarist and as such was employed backing a number of singers, reportedly including Gene Vincent and Conway Twitty while they were in England. Early in 1960, Sheridan performed in a package tour of the United Kingdom which also included Gene Vincent and Eddie Cochran. On April 17, Vincent and Cochran rebuffed his request to ride along with them to the next venue, but he thereby escaped the road accident which would leave Cochran dead and Vincent badly injured. He also played guitar for Cherry Wainer on her recording of "Happy Organ".

Vincent Eugene Craddock (February 11, 1935 – October 12, 1971), known as Gene Vincent, was an American musician who pioneered the styles of rock and roll and rockabilly. His 1956 top ten hit with his Blue Caps, "Be-Bop-A-Lula", is considered a significant early example of rockabilly. He is a member of the Rock and Roll and Rockabilly Halls of Fame.

Vincent Eugene Craddock was born in Norfolk, Virginia, on February 11, 1935. His early musical influences included country, rhythm and blues and gospel music. He showed his first real interest in music while his family lived in Munden Point, Princess Anne County (now Virginia Beach), Virginia, near the North Carolina line, where they ran a country store. He received his first guitar as a gift from a friend at the age of 12.

His father, Ezekiah Jackson Craddock, volunteered to serve in the U.S. Coast Guard and patrolled American coastal waters to protect Allied shipping against German U-boats during World War II. His mother, Mary Louise Craddock, maintained a general store at Munden Point. Craddock's parents moved the family and opened a new general store and sailor's tailoring shop in Norfolk.

Sir James Paul McCartney, MBE, Hon RAM, FRCM (born 18 June 1942) is an English musician, singer-songwriter and composer. Formerly of the Beatles (1960–1970) and Wings (1971–1981), he has been described by Guinness World Records as "The Most Successful Composer and Recording Artist of All Time", with 60 gold discs and sales of over 100 million albums and 100 million singles. With John Lennon, George Harrison, and Ringo Starr, he gained worldwide fame as a member of the Beatles, and with Lennon formed one of the most celebrated songwriting partnerships of the 20th century. After leaving the Beatles, he began a solo career and later formed the band Wings with his first wife, Linda Eastman, and singer-songwriter Denny Laine.

According to the BBC, his Beatles song "Yesterday" has been covered by over 2,200 artists—more than any other song. Wings' 1977 release, "Mull of Kintyre", became one of the best-selling singles ever in the UK, and he is "the most successful songwriter" in UK chart history, according to Guinness. As a songwriter or co-writer, he is included on thirty-one number one titles on the Billboard Hot 100, and as of 2012 he has sold over 15.5 million RIAA certified units in the United States.
