Prior to the recording process of Slip Of The Tongue, Adrian Vandenberg sustained a serious wrist injury, making it impossible for him to play without experiencing great discomfort. After Coverdale waited long enough for Vandenberg to heal, he had no choice but to find a new guitar player to finish the album. Coverdale chose ex-Frank Zappa and David Lee Roth guitarist Steve Vai. Coverdale was unfamiliar with Vai's work with Zappa or Roth, but had seen him in the 1986 film "Crossroads", in which Vai had greatly impressed Coverdale.
The woman, who appeared in many Whitesnake music videos around 1987, is called Tawny Kitaen. She's a model and an actress, and she married David Coverdale in 1989, but they divorced in 1991.
