scraper", and collected over two-hundred folk tunes in two books, the Northampton Manuscripts Nos. 12 and 13. As well as collecting folk tunes, Clare also collected many folk songs which are recorded in the Northampton Manuscript No. 18, and the Peterborough Manuscripts B4 and B7. According to George Deacon, the Northampton Manuscript No. 18 contains "more polished and refined versions" of songs which were originally written up in a rougher form in the two Peterborough Manuscripts, B4 and B7. Deacon's research led him to view the two Peterborough manuscripts as more authentic, inasmuch as they showed, "less conscious interference from the poet in Clare" than the versions of the songs in the Northampton manuscript. Since Clare's death, many of his poems have been set to music by classical composers, and, more recently, by contemporary singer/songwriters working in the acoustic and folk genres. However, at least one of Clare's poems was set to music in his lifetime, although Clare arrived in London too late to attend the performance. According to Professor Simon Kövesi, "The Meeting ... [was] Clare’s first poem to be set to music and performed on stage. The performance by singer Madame Vestris was at Drury Lane Theatre on 19 February 1820; the song was threaded into the pasticcio opera The Siege of Belgrade. Clare just missed the show, arriving in London for his first visit to the capital a short while after. Clare wrote that ‘on the night we got into London it was announcd in the Play Bills that a song of mine was to be sung at Covent Garden by Madam Vestris and we was to have gone but it was too late. I felt uncommonly pleasd at the circumstance’." Songs and tunes collected by Clare in the Northampton Catalogue The Catalogue of the John Clare Collection in the Northampton Public Library with Indexes to the Poems in Manuscript was compiled by David Powell and published by the County Borough of Northampton, Public Libraries, Museums and Art Gallery Committee in 1964. Included in the catalogue are the two books of folk tunes (MSS 12 & 13) and the book of folk songs (MSS 18).
