An event billed as A concert for the Children’s Hospital, Great Ormond Street, held in London on 14 May 1880, featured a performance of Bernhard Romberg’s Toy symphony in which prominent London musicians appeared performing with various mechanical birds and toy instruments; all but two of the musicians in the ensemble played instruments other than those that they were accustomed to performing on.
This according to “Famous Victorians in a toy symphony” by Herbert Thompson (The musical times LXIX/1026 [1 August 1926] pp. 701–702; RILM Abstracts of Music Literature 1926-888). This issue of The musical times, along with many others, is covered in our RILM Abstracts of Music Literature with Full Text collection.
