On each of the concerto recordings published in Hatto's final years under her name the conductor's name was given as "René Köhler", and Barrington-Coupe provided a detailed biography for "Köhler". The information given there has not withstood careful scrutiny. The conductors whose work is represented on the concerto recordings credited to Hatto and Köhler are now known to include Esa-Pekka Salonen, André Previn and Bernard Haitink, while the orchestras, claimed to be the National Philharmonic-Symphony and the Warsaw Philharmonia, are now known to include the Vienna Philharmonic, the Philharmonia, and the Royal Philharmonic.
