My chapter did this for recruitment a couple years ago... Still cracks me up that they didn't realize that Britney didn't write the song originally.
Silly girls...
I can't remember all of the words, it was such a while ago, but I'll do my best. Of course you'll want to change the words to fit your chapter... our local colors are pink and white, and our local mascot is the lamb, thus the "pink" and lamb references.
When I came to UCR, I knew instantly
The Riverside Gamma Phi's just can't be beat
With sisterhood so strong
The fun lasts all year loooong <stretch it out>
I could tell that I would belong
when I saw the Pink
(yeah the pink)
Singin'
I love Gamma Phi
There's never been a house that can top us baby
I love Gamma Phi
So come and sing along with G Phi B
The pink carnations, wooly lamb and crescent moon
Are in our hearts and we want to share with you
<can't remember the words here>
When I saw the Pink
(yeah the pink)
Singin'
I Love Gamma Phi
See the crescent moon shining so bright baby
I love Gamma Phi
So come and join the fun with G Phi B
<Get louder>
I Love Gamma Phi
See the crescent moon shining so bright baby
I love Gamma Phi
So come and join the fun with G Phi B
If I find the words to the rest, I'll edit the post
