I got a DVD from www.singscreen.co.uk and it is working great. It gives you 12 music videos as normal, then the same 12 with lyrics on the screen to sing along to (not karaoke) and then the same 12 again this time with Trivia & Facts about each video as the video plays. They only have 3 DVD's so far but I do think they are something a little different, and I am going to stick them on every now and again during my gigs.
Cool! Not quite "Pop up video", but cool just the same.
Wonder if it's legal to purchase from the US.
I used to love that show back in the day.
