From this point Messiah from Scratch became an event organised primarily for the benefit of choral singers, and the roster of works performed at the Royal Albert Hall grew.
By the end of the 1990s, Requiems by Brahms, Mozart, Fauré and Verdi were taking their place alongside performances of Orff's Carmina Burana, Elgar's Dream of Gerontius and Vivaldi's Gloria.
At a summer event in 1999, The Really Big Chorus gave the first performances of Sing!, a new composition by Sir David, a choral setting of his own words to Widor's Toccata, which was played on the Royal Albert Hall organ by Jane Watts, with additional material for the orchestra.
On 11 September 2011, Karl conducted TRBC singers in a memorial concert of The Armed Man at the Avery Fisher Hall (part of the Lincoln Center), New York.
The work, entitled In Praise of Singing (for soprano and baritone soloists, chorus and symphony orchestra) was commissioned by Don Monro and will receive its first performance on 13 July 2014.
