Dec. 30 
Dear Nicholas --
I admit I'm an ingrate. Particularly since my 'Concerto' does end with a brilliant gliss-----ando, tho not exactly in C major. But my pragmatic mind refuses to see anything other-worldly in this: it simply goes to prove that either you are a very trite dreamer or I am a very banal composer!
I am dividing my days between practicing the piano and writing the definitive article on Jazz for 'Modern Music' and looking forward to the end of January.
But the laconic announcement of your sticking in the mud next week sent me completely ga-ga. A Boston Symphony concert without you somewhere in the near vicinity seems incredible. I console myself with the thought of January 12th or thereabouts.
In a few days I shall occupy myself with the program notes and send them to you to hand on to Mr. Hale, if you will.And when you do come to N.Y. dont fail to ring me up (Susquehanna 05 28)
P.S. To-morrow night, a New Year's Eve party at the Knopfs -- why can't you be there so that we can be poisoned to-gether!
