Off message but I thought I might as well add to the nation's obession with Strictly Come Dancing (which of course I do not share) and there is a union connection!
My UNISON Branch administration officer Sarah and her Partner Paul (who is a union activist as well) are champion Jive dancers.
With a friend they have develped a "iphone dance app" in which they appear and dance. See Youtube video and buy for your phone here http://www.dancerstudio.mobi/SitePortalPage.aspx?siteid=9&cfid=0&did=208 and http://itunes.apple.com/gb/app/dancer-studio/id471703495?mt=8
So if you want to play a Jive game or practice your own Jive moves while waiting for the bus or during your lunch break then give it a go.
