Sisters Urge Stones To Get Back To Work For Wood's Sake

In recent months, Wood has spent time in rehab, split with his wife Jo, and set up home with a Russian girlfriend 40 years his junior, and Richards siblings Alexandra and Theodora blame Wood's personal life turmoil on the fact there's no band activity to keep him grounded and busy.

The worried sisters insist all will be well for Wood as soon as he gets back to work on a new record and tour.

Alexandra tells the New York Daily News, "We are all a family. We're all tight-knit. I think that once they get in the studio together it won't take that much - just a simple stroke of a chord, and that's it."

Theodora adds, "I am crossing my fingers."
