We never sang Phi Mu Castle I keep hearing about it though, as it seems to be a favorite of many chapters.
The main songs/chants that we did...
With a P, with a P, with a P-H-I, etc.
Linger
Sisters
I am embarrassed to say that I can't remember the names of the other main songs we sang. I am sitting here humming them as I am typing but I can't remember titles!!
