Q:Given the following context:  Boult, unlike many of his contemporaries, preferred the traditional orchestral layout, with first violins on the conductor's left and the seconds on the right. Of the practice of grouping all the violins together on the left, he wrote, "The new seating is, I admit, easier for the conductor and the second violins, but I firmly maintain that the second violins themselves sound far better on the right. ... When the new fashion reached us from America somewhere about 1908 it was adopted by some conductors, but Richter, Weingartner, Walter, Toscanini and many others kept what I feel is the right balance."This care for balance was an important feature of Boult's music-making. Orchestral players across decades commented on his insistence that every important part should be heard without difficulty. His BBC principal violist wrote in 1938, "If a woodwind player has to complain that he has already been blowing 'fit to burst' there is trouble for somebody." The trombonist Ray Premru wrote forty years later, "One of the old school, like Boult, is so refreshing because he will reduce the dynamic level – 'No, no, pianissimo, strings, let the soloist through, less from everyone else.' That is the old idea of balance."As an educator, Boult influenced several generations of musicians, beginning with his conducting class at the Royal College of Music, London, which he ran from 1919 to 1930. As no such classes had been held before in Britain, Boult "created its curriculum from out of his own experience. ... From that first small class has come all the later formal training for conductors throughout Britain." In the 1930s Boult ran a series of "conferences for conductors" at his country house near Guildford, sometimes helped by Vaughan Williams who lived a few miles away. From 1962 to 1966 he again taught at the Royal College of Music. In later life, he made time for young conductors who sought his counsel.  Among those who studied with or were influenced by Boult were Colin Davis, James Loughran, Richard Hickox and Vernon...  answer the following question:  What was the last year Boult taught at the Royal College of Music?
