one trick pony lyrics

I'm a one trick pony, if you will
I got a one track mind with a heart that's real
And don't forget I've got tunnel vision
For something much bigger than superstition
Call me hard headed for the One that changed me
Say what you will, it will not phase me
No need for anything up my sleeve
There's just one thing that I'll ever need

You are my one and only
You are my one and only
Oh, I'm a one trick pony

If I hear just one more time
That I should try and be more open-minded
I think I just might scream
The world says this is all there is
Yet I believe the One who says there's life after this
Now tell me how much more open can my mind be?
