With the recent news of Fleetwood Mac's upcoming 2013 tour comes yet another wave of questions regarding the possibility of keyboardist Christine McVie ever rejoining the band -- and forcing Lindsey Buckingham to tell us, once again, that it's probably never going to happen.

"Well, that’s a good question," said Buckingham when CBS asked him if the band would ever welcome McVie back to the lineup. As he went on to point out, not only is it an exceedingly remote possibility (as Stevie Nicks recently put it, it's as likely as "an asteroid hitting the earth"), but Buckingham is actually having more fun now that the Mac is a quartet.

"It’s an odd thing for me, in many ways I’m having a better time in the band as a foursome, only because it opens up a range of things that I can do," he continued. "Except for maybe ‘Don’t Stop,’ we don’t do a lot of her stuff. It opens up the amount of material we can play, it allows me to be more of a ‘guy,’ to be more of who I am up there."

Of course, Buckingham hastened to add, that doesn't mean he doesn't miss McVie's contributions to the group. "I would be shocked if she ever expressed any interest to do anything with us," he mused. "Shocked and pleased."

In Buckingham's eyes, it's all about what McVie wants -- and that doesn't include having anything to do with her former life as a pop star. "She ended up getting a divorce, she ended up selling her house in L.A., she moved back to England, she quit the band, she sold her publishing. She didn’t necessarily have to burn as many bridges as she did," Buckingham explained. "Everyone sometimes wonders whether or not there might have been more of a middle ground for her to strike, not necessarily in terms of her staying in Fleetwood Mac. But she just wanted to reinvent herself. She seems to want to lead the antithesis of the life she led before, and I don’t pretend to understand such a radical change, but it was obviously something she needed."
