I have been working on this and i must have sent 20 or so emails to WSM sport but not a single reply. Nothing on the ACC web site or the Aberdeen Council web site.
Someone did say something on AM.com about it happening but that could just be gossip.
I found a pdf file on the Aberdeen Council web site that stated that WSM sport are in the planning for a Scotland v spain match incl Rafa but it is dated March 2006. There is also something on the lta site about registering your interest in this years event but nothing much else comes up when I googled.
