Material concerning the [then largely secret] relationship between Muriel Angus Mann and the composer Sir Granville Bantock. Includes correspondence from Bantock to Muriel, programmes for concerts performed by Bantock, newspaper articles about Bantock, music scores, and some photographs, including an album depicting Bantock's trip to Sri Lanka in 1937. The correspondence covers 1936-1940 and documents Bantock and Muriel's love affair, and his involvement with her and her three daughters. The letters detail Bantock's travels as well as his interest in music and concerts. There are some periods when letters were not written, perhaps notably when Bantock spent time with Muriel, in early 1939, in Charleston and Sapphire, North Carolina.
The collection also includes a sapphire ring that Bantock gave to Muriel and which she wore until her death; papers relating to Muriel's Honorary Degree from Trinity College of Music, London; sheet music with the initials 'MAB' added ['MAB' meaning 'Muriel Angus Bantock', the couples' code]; and the score for 'Memories of Sapphire' that was written for Muriel in February 1939.
Whilst the date span of the collection is 1909-Late twentieth century, the majority of the material dates from between 1936 and 1940, the period in which Bantock and Muriel's relationship took place.
