Our chapter sings "Picture a Girl" and "Phi Mu Castle." I've never heard of a song called "Sisters," but I plan on finding it for the fall.
"Linger" gets used during recruitment.
As for cheers...we use "With a P", "Badoom badoom", "Are you a Phi Mu", and a brand-new one (to my pledge class, anyway) that's been really hard to learn for recruitment called "I will be T-R-U-E" (I think). It goes:
I will be T-R-U-E true to P-H-I-M-U Phi Mu
And I will L-O-V-E love her just as you will D-O do
And if you want F-U-N fun she is the O-N-E the one...!
And you will find your jolly times have B-E-G-U-N begun!
Anyone else do that one?
