Rhys Griffith is a senior archivist at Hereford County Record Office, where a rare piece of medieval music has been found during a clear up of the archives.
The find came as a complete shock to staff as it was being used as a protective covering for other later documents.
Mr Griffith says it's a priceless piece of evidence giving a glimpse of Hereford's medieval history.
