Dual Video Single audio track presentation

I’m looking at automating the following, we have kids Christmas program coming up where we in the past we displayed the lyrics to the words of the songs in power point and presented them strictly to the kids on the stage via two large CRT TV’s and at the same time a second computer running a video file with the graphics only mo lyrics and sound track mixed together where the video/pictures are presented behind the kids and the audio track is the encampment track which the kids to sing together with. Not sure if there is a solution out there where I would be able to have two video time lines feeding two different video feeds and a audio track running from one computer and here is a kicker which does not cost much or next to nothing.
