Photo editing

I'm looking for someone to:

Take image1. Replace the giant TV screen that is circled in red with image2. Please note all the wires, cables and microphones hanging in image1 still need to be there, partly covering the screen.

Image1b was done very badly, but is the right principle.

Rather than starting with image1, download original jpg from this page, preferably without the play button in the bottom left corner:
http://www.bbc.co.uk/programmes/articles/4ffY28QxcN4nv0hzdvC5Rrd/bso-resound-the-first-disabled-led-ensemble-to-perform-at-the-bbc-proms

Is it then possible to use the new image without crediting you?

Many thanks, Alex
