MacFarlane, John: - John Macfarlane is a retired English born physician and musician whose specialist training in rheumatology followed gaining his clarinet performing and teaching diplomas from the Royal College of Music in London, having been taught by Thea King as an external student. Combining these two specialisms was often tricky and, having moved to the Netherlands in 1978, a day of clinical work was sometimes succeeded by playing clarinet and saxophone in the orchestra pit of an Amsterdam theatre. In addition to the occasional spot of professional playing on clarinet, basset horn or bass clarinet, he has conducted choirs and orchestras, has edited works by others for a publisher, has taught the clarinet, has made numerous arrangements and even dabbled in composition. He has even had the good luck to have played clarinet with Jack Brymer and Alan Hacker. A lifelong curiosity into unusual instrument combinations has led him to acquiring music of untold variety, often 20th century, much of which is the basis for this book.
