MultimedaK, a MultimedaK publisher, decides to produce a DVD containing selected poems written by Andrew, Belinda and Clarence. Andrew is still alive, Belinda died some 20 years ago and Clarence has beer dead for 80 years. Diana, a famous self-employed literary critic has been commissioned by Multimedak to select the poems to include in the DVD and to write some material giving a critical appraisal of each poem. MultimedaK s editing manager, Edward, selects some music written by Frances, who died 62 years ago, to use as background music. George, an actor, is commissioned to recite the poems in front of a studio audience. A selection of modern photographs of the poets' homes and favourite haunts, taken by Harriet, is to be included in the work, with her permission. There is also some old footage of Belinda being interviewed live on ICA television. MultimedaK's employees created the computer programs to access and display the works and the hypertext links. Assuming that there has been no subsequent transter of the various copyrients except on te aeatn copyright owner, what permissions will be required by MultimedaK?
