As Terry Wogan will point out, the proceedings are less dominated by the quality of the music than they are based around the changing and expanding political landscape of Europe.
Along with France, Spain and Germany, the UK are guaranteed a place in the final as they are the largest contributors to the European Broadcasting Union, which runs the contest.
But a place in the final doesn't guarantee votes - not when there are closer ties between Scandinavian and Baltic states (Denmark, Sweden, Finland, Latvia, Lithuania) and the ex-Yugoslav states.
It may not be brilliant entertainment - but it'll be more fun (and cheaper) than the poorly reviewed Da Vinci Code film that went on general release last night.
UPDATE - if you're not in the UK, and don't have access to a broadcast feed, try the online feed from the official Eurovision website (though there's more back stage news from the unofficial ESCtoday.com site, which has been running for several years).
