One Trick Pony

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?
