Would be nice to hear some Christine tracks from "Behind The Mask" - such as "Save Me" or "Skies The Limit"
I think "Skies The Limit" could work as a concert opener to showcase Christine, and then go into "The Chain" if they really really refuse to drop it
"Save Me" is an underappreciated Christine McVie gem, IMHO - it's fast enough in tempo, and feels like a classic FM track that even the casuals will get into it!
