What happens when I grow old? Will your heart still race for me?

What happens when I grow old?

Will your heart still race for me?
Or will it march to a new beat?

Would we still walk hand in hand?

If I suddenly went blind,
Would you still look in my eyes?

Would you still stand by my side?
And would our flame still burn so bright?

There’d be no reason to think twice
You’d be my sun; you’d be my light.
