|Handel Commemoration in|
From Wikipedia: Handel's festival or ‘Commemoration’ took place in Westminster Abbey in 1784, to commemorate the twenty-fifth anniversary of the death of George Frideric Handel in 1759 and was organized by John Montagu, 4th Earl of Sandwich. The Concert of Ancient Music took the form of a series of concerts of Handel’s music, given in the Abbey by vast numbers of singers and instrumentalists.
The commemoration established a fashion for large-scale performances of Handel’s choral works throughout the nineteenth century and much of the twentieth. E.D. Mackerness in A Social History of English Music described it as "he most important single event in the history of English music."
Handel is honored together with Johann Sebastian Bach and Henry Purcell with a feast day on the liturgical calendar of the Episcopal Church (USA) on July 28. He commemorated as a musician in the Calendar of Saints of the Lutheran Church on July 28, with Johann Sebastian Bach and Heinrich Schütz.
