A Mary Hopkin Session Or Two

During the recording for "Abbey Road" in 1969, both Paul McCartney and Ringo Starr took some time out of the Beatles' recording sessions in order to create a new single for their Apple Records artist Mary Hopkin. An undated session was held in July 1969 and another session was held on August 17 1969. Both sessions took place at EMI Studios although the studio number is unknown.
Two songs were recorded; a cover version of "Que Sera, Sera" made famous by Doris Day and written by "Livingston/Evans" - which may be the "in joke" throughout the Get Back/Let sessions and Ms. Day is even mentioned on the track "Dig It" from those days as well as some spoken references during that period. But I digress. The B side of the single would be "The Fields of St. Etienne" written by the Apple in-house songwriting team of "Gallagher/Lyle".
Both "Que Sera, Sera" and "The Fields of St. Etienne" were produced by Paul McCartney although on the back over of Mary's "Those Were The Days" Apple LP the credit is incorrectly listed as produced by Mickie Most. Paul plays the acoustic guitar on both songs; Mary also plays acoustic on the B side. Ringo plays drums and percussion for the A and B sides as well as tambourine, handclaps, etc. There is an orchestral style overdub on the last chorus of "Que Sera,Sera" or it may be a keyboard with sustaining chords. Also it is a mystery as to who arranged the orchestration for "The Fields of St. Etienne" - is it George Martin? Richard Hewson? Anyway, the other mystery is the male voice added to the last verse in the B side.
The single was originally released in France in 1969 but released in North America as Apple 1823 as well as being released commercially on the compilation Apple LP "Those Were The Days" as well as being re-issued on compact disc in 1995 and on the remastered Apple box set on CD in 2010.
