Mr. Paul Sacher,

Schoenenberg,

Pratteln, Basle.

Dear Mr. Sacher,

               Raphael Kubelik is anxious to perform the SINFONIA CONCERTANTE by Martinu in Amsterdam in the near future (I do not know the date yet). I wonder if you would mind if we gave him permission to do this? Please let me know. We have to consider that Kubelik is a fellow-countryman of Martinu and you, on the other hand, have already done so many first performances of Martinu’s works. Please let me know your point of view quite frankly.

                                                           With kind regards,

                                                                                         Yours sincerely,

                                                                                         [podpis]

                                                                                         ERWIN STEIN.
