Does anybody know for certain as to the state of richie at the unplugged session. Additionally, does anybody know about richie's stint in rehab.
I found an article online and it said:

Bon Jovi was supposed to jump start the return of Unplugged to MTV, but their taping of the show on Tuesday was a complete and utter disaster, multiple sources confirm exclusively to PerezHilton.com.

Bon Jovi recorded their Unplugged - which will air cross-platform on MTV, VH1 and CMT - in Brooklyn on Tuesday night for about 400 fans or so and Richie Sambora was blitzed the whole time.

“They had a whole bunch of musicians on stage for most of the night to cover his mistakes on the guitar and would turn his mic off so he couldn’t be off key,” a spywitness tells us.

Seems Denise Richards‘ ex-boyfriend was partying too hard before the show!

Towards the end of the show, Jon Bon Jovie and Richie were on stage alone and Jon goes on to tell the story about how they started acoustically at the MTV VMAs once and…. “This is how Unplugged started….”

A shocked source reveals, “As Wanted Dead or Alive started, Richie couldn’t play along! During the song Jon stops and makes Richie start again and after the second take was finished the show was supposed to be over but Jon had the whole band come on stage to re-record the song a third time so Richie couldn’t mess it up! Jon was clearly upset, but kept it together and handled it like a true pro!”

The folks at MTV will have fun editing this one!"
