On The Beatles' first visit to Hamburg, Germany in 1960, they met rock and roller Tony Sheridan, and became friends with him. On their second visit, in 1961 (now minus Stuart Sutcliffe), The Beatles backed Sheridan in a series of stage performances. It is sometimes said that German Polydor agent Bert Kaempfert personally saw Sheridan with The Beatles, but others report that a friend of Kaempfert's suggested that he bring them in to put down some recordings. Either way, he produced the material with Karl Hinze engineering. While they recorded a number of songs together (as well as alone), few of them actually made it on to the album, with Sheridan re-recording many of them. The Beatles are known to appear on "My Bonnie" and "The Saints" (this pair was also released as a single, see below). The version of "Swanee River" on the album has sometimes been said to feature The Beatles, however that version is in fact not included here, and it is not known whether the original recording still exists.
Legend says, in 1961, Raymond Jones, a young man from Liverpool, made a request for a copy of the "My Bonnie" single, which brought The Beatles to the attention of then-record store manager Brian Epstein, and set in motion the events that would lead him to become their manager. After The Beatles became successful, the eight tracks The Beatles worked on and some other Beat Brothers material were issued on an album in 1964 titled The Beatles' First.
