Lyrics
Glory (glory) is calling your name, Victory's for the brave, Resilient souls who persist.
Persist... [×4]
Towards (towards) your goal, Walk the edge, Rewards await at the end, Glory for those who persist.
Go the distance, For the mission, Eyes on the horizon, horizon.
Keep it up. [×2] Don't give up. [×2] [×2]
Keep it up. [×2] Never give up.
(Persist) Glory is calling your name, (Persist) Victory's for the brave, (Persist) Resilient souls who persist.
