(FROM BILLBOARD) ? Fleetwood Mac singer/guitarist Lindsay Buckingham told Billboard the band was surprised by recent claims made by Sheryl Crow that she and the group ”definitely have plans for collaborating in the future.” Crow, who is friends with Fleetwood Mac’s Stevie Nicks, would presumably fill in for Christie McVie, who retired from the band in 1998. Buckingham acknowledges that a future collaboration is a possibility, but he says nothing is written in stone. ”I think we were all a little surprised [Crow] was announcing that to the world with such certainty,” Buckingham said to Billboard. ”We have talked about the possibility of bringing another woman into the scene to kind of give Stevie a sort of foil and shake it up a little bit. [Crow] was certainly a name that has come up. We’ll have to see.” (Billboard)
