"If I leave here tomorrow
Would you still remember me?
For I must be travelling on now,
'Cause there's too many places I've got to see.
..........
'Cause I'm as free as a bird now,
And this bird you'll never change.
And this bird you can not change.
Lord knows, I can't change.
Lord help me, I can't change."
A valid question given the context. I enjoy photographic work like this. My initial response was one of wonder. I asked MYSELF the same question, jumped in and came up with my own interpretation. This would make a good side challenge...
