Forgive me if I have a word or two wrong... I've never seen it written down anywhere, and this is from memory:
Father, we thank thee
Homage we pay
For the new blessings we receive each day
Bless thou this food, and make us strong and true,
Happy in the bond of dear Phi Mu
If you are able to audio chat on AIM, I'd be happy to give a singing demonstration. Haha.
