[4] By 1894 the union had over two thousand members, and another seventeen branches had opened, these were focused in Scotland, the Midlands and the North of England.

[4] The union's first General Meeting was held in Manchester in 1893, the first conference took place in Liverpool the following year where the elected committee was appointed.

[4] In 1909 a protest was held, through a barge on the Thames was covered in banners raising the issues that musicians were facing in the United Kingdom passing the House of Commons.

[4] Williams called off the disputes and strike action that branches were to take part in, Williams spoke with the management of halls and theatres in the hope of keeping the establishments open he agreed that every union member would take a pay cut to try and keep the buildings open during the war.

[4] This was partly due to musicians, like women, amateurs and foreigners being allowed to fill spots that they would not typically have been able to apply for.

[4] Musicians had to find ways to adapt as jobs became more varied and they often had to learn new instruments and be flexible in order to keep their employment.

[4] The BBC had a significant number of orchestras, these were broken down either by their location, or their style and were highly coveted positions in the music industry.

[4] The transition from silent films to 'talkies' meant that fewer musicians were employed at cinemas as sound was now pre-recorded.

[4] The Jazz Singer was the first of the talkies, and was first screened in the USA in 1927; by 1929 Fox had stopped making silent films and the rest of industry soon followed.

[4] In the early 1980s the BBC were forced to make cuts due to the deficit of their income because licence fees had not kept up with inflation.

[4] Five of the BBC's orchestras were to be disbanded due to the cuts, which equated to 153 full-time and 19 part-time jobs, this was a blow to the union who wanted the members to strike.

[4] When Dennis Scard came into the role with the union, he saw that there was an issue with the competition of foreign orchestras taking the jobs as they would accept less wages which promoters were eager to exploit.

[4] Kay was receiving a lot of support, but Scard had not told anyone that he had been diagnosed with cancer, which meant he had had an operation and was undergoing radiotherapy during the campaign.

On 5 February 2020 the union's executive passed a motion extending Trubridge's term without re-election to 15 January 2025, his 68th birthday.

The union confirmed that the next election for the role would now go ahead at the end of Trubridge's current term of office on 27 March 2022.

Sir Henry Wood and Lady Wood, and the composer Baron Frédéric Alfred d'Erlanger were among those who attended a ceremony to lay the foundation stone of the musicians' home on 10 June 1932, where the arrival of the Baron was serenaded by 10 trumpeters, 10 trombonists and 10 drummers; musicians were present from the London Philharmonic Orchestra and from the Covent Garden Choir.

The Baron used a silver trowel (which was then gifted to him as a souvenir) to lay the home's foundation stone, still present, which bears only his name and the date the stone was laid, making no reference to Sir Henry Wood or to the purpose of the house; the write up of the ceremony to lay the foundation stone that was published in the Leatherhead and Dorking advertiser records that it was planned to build more properties in the grounds, for example a musicians' orphanage, noting that it had taken 10 years from 1922 to 1932, to raise the funds for the site and the first home there.

The planning portal of Mole Valley District Council records that permission was applied for in 1948 for three more homes on the site.
