I had memories of a movie I saw when I was younger about a group of teens (maybe 3 or 4 if I am not mistaken) during an alien invasion. I can't quite remember what time this took place in, but the movie was full color and if I remember right it wasn't very futuristic. I remember the group of teens going off somewhere and staying in a cabin or some small house during the movie. It started off I believe with the teens at a camp of some king before the invasion took place. They were sent to the camp possibly and then that all happened.
I can remember the song 'ain't no mountain high enough' being featured in there when one of the kids was missing his mother he was singing it because it was their special song for if he ever felt lonely.
