Bon Jovi: What do you got when Richie doesn't play the opening?

Ok, so I watched the video from the Private show at the PC Richards Theater in Tribeca and the first thing I though was why is Bobby Bandiera playing the intro, that's Richie's job!

I don't play guitar so my knowledge of things guitar playing and things is limited.  But I got an education from my fellow Tweeter @MikaHeartRS .

"there could be several reasons like the intro riff is played throughout the whole song and it uses a capo where as the chorus and the solo are played on an open tuning WITHOUT the capo and trust me its a pin in the ass and senseless to be taking in and off a freakin capo, having a 2nd guitarist the capo part can be played AND the choruses and solo in open tuning on another one so doesn't have to annoy himself with the capo issue"

Ok. So I understand it's something that goes on the guitar but since I'm Guitar mentally challenged, and Google Instant is my new BFF here's what I found out:

Anyway, a guitar capo is a clamp that you stick on different frets of the guitar to change the pitch or key of the open strings. Each fret on the guitar is a half step, therefore, if you put a capo on the 1st fret, all of the open strings will sound a half step higher than normal. This makes changing the key of a song very easy. Have you ever seen a song which had really weird chords that you didn't want to really mess with? With a capo, you can change the key or pitch of your guitar and make those tough chords easier to play.

For example, if you have a song in the key of G (usually, the first chord of a song gives away the key of the song) with the chords G, C, and D, you could change the song into the key of A. You would just put a capo on the 2nd fret, and play the chord shapes G, C, and D. These chord shapes will now sound a whole step higher. They will sound like the chords A, D and E.

When learning more about using a capo, there are 2 basic ideas to understand. Chord shape, and chord sound.

No matter what fret you have the capo on, when you play a G chord shape, in your mind you will always think of it as a G chord. This is a G chord shape. If you were to capo the guitar at the 2nd fret and play a G chord shape, then the chord sound would be that of an A chord.

This is the main idea of using a capo. You are using familiar, maybe even easier chord shapes to get the chord sound of less familiar, more difficult chords. If you have a Bb chord in a song, you could put the capo at the 1st fret, and play an A chord shape. But you will get a Bb chord sound.

So here is the live version from the private show, you've probably already seen it, so watch it again.
