I think it's probably more of a chant than a song? One of my sisters taught it to our chapter, and I've never heard it anywhere else in Kappa. Her mom, who was a Kappa, used to sing it to her when she was little. You do cute hand motions to it:
Go Fraternity: hold hands out in front of you, palms facing out and fingers down
Wear the golden key: make a box with your forefingers and thumbs together, and hold to your chest where the key goes
Be a fleur de lis: put both arms above your head, palms together to make the top of the fleur de lis. We used to take group pictures in this pose -- it was before anyone was doing hand signs.
