Real Life - album/single version

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...

I've noticed a difference. It's very slight but the single version has a piano that isn't in the album version. I forget what else I noticed but it's more poppier mixing.
