Beatles collaborator and 'teacher' Sheridan dead: family

The singer/guitarist, who died in Hamburg, performed on some of the Beatles' earliest recordings after meeting John Lennon, Paul McCartney, George Harrison and original drummer Pete Best in Germany in the early 1960s.
He was then a well-known figure in the Hamburg club scene and joined forces with the quartet to record tracks including "My Bonnie," "The Saints" and "Ain't She Sweet" under the name Tony Sheridan and the Beat Brothers.
McCartney called Sheridan "The Teacher" due to the influence he held over the band in their coming-of-age spell playing clubs in the city's red-light district.
