I plant a flower, plant a tree
Plant your hopes and plant your dreams
And let them grow until… (5, 4, 3, 2, 1)
I’ll take you somewhere that is near
Seas of blue and fields of green
May the heartaches soon be healed
I’m just a woman but I’m for real
As strong as every man can be
So put your faith in me…
I'm what I am and what you see
Only say the words that I would keep
I'm one of you
