Grimsley's alma mater was composed and written by Herbert Hazelman in 1949. Mr. Hazelman was the Greensboro Senior High Band Director for 40 years. The music building is now named in his honor.

All hail to thee

Our alma mater strong

We'll sing thy praise through all the days

with this triumphant song

All hail to thee

And as the days go by

We'll pledge our faith and love and loyalty
