In a second hand shop I found a single of Real Life that I had never seen before. It's got the white cover with the EdTV-style Bon jovi logo, but only two tracks. It says 1.radio version 2. album version

I listened to it but couldn't hear a difference, so I didn't listen to the whole songs. They sounded exactly the same and were both 3.47 long. Strange. It wouldn't make sense to put the same song on one single twice...
