On which 'Say You Will' songs does Christine play?

[nicepace]

And does she do any backing vocals or is it just keyboards? I know this has been discussed before but I forget. I am making an attempt to actually listen to 'Say You Will' (for the second time) and being alerted to Chris' keyboard playing would perk up the listening experience for me.

If anyone would like to comment on what her keyboard playing does for those songs, it would make this a real thread, not just a boring request for information from a Christine completist.

I was going to post this in the Rumours forum but I lost my nerve.
