Random videos followed by selected videos from array

I've been making a site that plays 60 random videos (without duplicates) one after the other. However, I'd like it to play certain videos after a certain amount of videos have been played. Once the selected video has been played, it then returns back to stepping through the random shuffled of videos. For example, '1,40,32,21,45,(chosen video), 59, 11,18,27,(chosen video) etc etc. It's important that the selected video's are not then included in the 60 shuffled videos. Hope that makes sense...I'm very much a beginner so any help would be much appreciated!

Thanks a lot :)
