 In March 1966, Epstein investigated the possibility of their recording the new album at Stax, where, according to a letter written by Harrison two months later, the group intended to work with producer Jim Stewart.The idea was abandoned after locals began descending on the Stax building, as were alternative plans to use either Atlantic Studios in New York or Motown's Hitsville USA facility in Detroit.Recording for the album instead began at EMI Studio 3 in London on 6 April, with George Martin again serving as producer.
