20. A method of producing a performance for viewing by a viewer, the viewer being provided with a device enabling the viewer to view an image of a performance in combination with a secondary performance component, the method comprising the steps of:
a) generating a primary performance component, the primary performance component being generated by a primary producer,
b) selecting a secondary performance component, and
c) enabling the viewer to view the primary performance component in combination with the secondary performance component during step (a).
21. The method of claim 20 wherein the primary performance component is performed by the primary producer before a live audience comprising the viewer.
22. The method of claim 20 wherein the secondary performance component is selected from a menu provided to the viewer by use of a telecommunication device.
23. The method of claim 22 wherein the secondary performance component is selected from the group consisting of a background still image, a background moving image and an alphanumeric sequence.
24. The method of claim 20 further comprising the step of producing a recording of the performance.
25. The method of claim 24 wherein the performance is recorded from a plurality of viewpoints.
The claims below are in addition to those above.
