Here in the UK a lot of big name artists often appear on ITV doing a 1 hour 'special' of their greatest hits. Rod Stewart, The Bee Gees, Neil Diamond and many more have done it in recent years.
I'd love it if Fleetwood Mac did one with Christine returning as a one off (although obviously would love her to do some shows with them too) - I could see this show doing really well and having a similar impact to The Dance reunion. She wouldn't have to travel far either
