You've come such a long, long way
And I've watched you from that very first day
To see how you might grow
To see what you might do
To see what you've been through
And all the ways you've made me proud of you

It's time now for a new change to come
You've grown up and your new life has begun
To go where you will go
To see what you will see
To find what you will be
For it's time for you to fulfill your destiny

The amount of joy and pride in Celestia's voice when she was singing drove me to this!
