Simpson's Alma Mater Song?

I'm the choir TA, and I'm sorting and organizing music, and I just came upon the Simpson Alma Mater composed in Seattle by Helen H. Lemmel on April 20, 1958. These are the words:

Thanks be to Him, our Sovereign Lord,
for you our Alma Mater, staunchly true to His Word;
faithful to declare His glory to the nations
and tell His good news around the world.

Hear the endless march of the countless feet to our doors,
seeking knowledge of the truth and life complete;
for Christ our life we're living and to Him our homage giving,
dear Simpson, our Alma Mater!
