Cheesy 70's song I have stuck in my head

Well this was at a camp that I went to two years ago. We sang this really old 70's song that the choral director found in the university's choral music library. He asked on of the chorus sectionals (my sectional) if we should sing it. Being the uncaring and silly teenagers that we are, we voted to sing it for the mid-camp concert. IT was soooooo fun!

sadly, I didn't go this past year in which they had sung this song for fun. I was so mad when I saw this on youtube, but I absolutely love this and sing along with it as much as possible.

(sadly, I don't really know how to insert a video. You should tell me. I dont do this often anyway)

The person who video-ed this (who I believe was my friend.. Judging on the position of the people around her.) And she put the camera on the piano a lot.

and ignore the people being off-pitch this was merely just for fun

I am sorry I had to put this on here.. I got bored.
