A system and method of delivering an information output to a viewer of a live performance. The information output can be displayed text or an audio description at predefined times in the live performance relative to stage events. A follower script with entries organised along a timeline, and metadata at time points between at least some of the entries is generated. The metadata is associated with stage events in the live performance. The system uses speech recognition to track spoken dialogue against the entries in the follower script, and the stage events, to aid in following the live performance.
