Thursday 22 June, and possibly the following day as well, was the likely date of The Beatles' recording session with singer Tony Sheridan in Hamburg.
The Beatles had been approached by orchestral leader and Polydor agent Bert Kaempfert, who wanted them as the backing band for Sheridan. On this day they performed, not at a recording studio, but at a converted stage at Hamburg's Friedrich-Ebert-Halle school.
The first song to be recorded was My Bonnie, a beat version of the old standard My Bonnie Lies Over The Ocean. It was followed by The Saints, a new arrangement of another old song, When The Saints Go Marching In.
The musicians also recorded Sheridan's self-penned ballad Why (Can't You Love Me Again), Hank Snow's Nobody's Child, and Jimmy Reed's Take Out Some Insurance On Me Baby.
Once the Sheridan songs were complete, The Beatles made two recordings of their own. Ain't She Sweet had lead vocals by John Lennon, and the second tune was a Lennon-Harrison instrumental titled Cry For A Shadow. Both recordings appeared on 1995's Anthology 1.
The Beatles were given 300 marks for the session, and the My Bonnie single - credited to Tony Sheridan and The Beat Brothers - was released in October 1961. It reached number five in the German charts.
Didn't they also record Sweet Georgia Brown? It was released as a single and on many compilations including one listed in the East German discography.
