I have recently been given a published copy of a piano concerto in C major by John Wearham. It was published in 1923. He seems to have invented a new type of pneumatic piano. One of his backers was Sir Vincent Caillard 1856-1930 to whom it is dedicated, who in turn was an acquaintance of Seymour Darlington from whose collection it comes. He in turn was married to Kathleen Bruckshaw. I am wondering if there is any further information about John Wearham?.
