Stevie Nicks opened up about why her decision to obtain an abortion in 1979 was paramount to Fleetwood Mac's continuance.

The continued survival of Fleetwood Mac following the group's landmark 1977 album "Rumours" came down to the fact that Stevie Nicks chose to have an abortion, the singer told CBS Sunday Morning on Sunday.

That is what makes me happy, and that’s why I’ll never stop touring. Because if I stop touring, then I’ll stop dancing. I go on a summer tour next year, and I [will] do 40 shows. That’s what Fleetwood Mac used to do.
