Rising up to the sound
Like thunder, shaking the ground
Power within, we're here to stay
On our own, we'll never fall

I BU, we're here to take flight
Through the clouds, we'll rise above
I BU, we're not alone
We'll rise up, and never stop

Through the darkest nights and storms
We'll never give up, we're strong
Striking fear in the enemy
We'll rise up, and never bow

I BU, we're here to take flight
Through the clouds, we'll rise above
I BU, we're not alone
We'll rise up, and never stop

Together we're stronger
Together we rise above
In the darkest hour, we'll light the way
We'll fight, and never surrender

I BU, we're here to take flight
Through the clouds, we'll rise above
I BU, we're not alone
We'll rise up, and never stop
