# Wake Me Up When September Ends

Summer has come and passed

The innocent can never last

Wake me up when September ends

Life my father‘s come to pass

Seven years has goes so fast

Wake me up when September ends

Here comes the rain again

Falling  from stars

Drenched in my pain again

Becoming who we are

As my memory rests

But never forgets what i lost

Wake me up when September ends
