What do I think of this?

Well Greece are in a right pickle. Some would argue that now isn't the time to send an upbeat olive tinged rouseabout effort to a European singing contest, having just been bailed out for a squillion euros by their neighbouring countries. But not I. Although unlikely to get many televoters from the Ruhr, enough little people from around the edges of Euroland should provide this generic plate throwing number a few votes.
Was that your phone? Ring tones in songs are not a growth industry. Crazy frog is not the way to go Greece. A bunch of wallopers will jump around in unison, whilst vainly trying to keep the energy up. This song "Opa" from Georgios Alkaios is not to be confused with his previous hit "Opa Opa" which I presume was twice as good. George is joined by his "friends" who are of course experts in hand clapping, leaping, "heys", and bouzouki, subjects which I presume every Greek schoolchild gets a GCSE in.
It will of course qualify with ease, but I can't see it having any real "Opa" come the Final. They would only throw it back if they won it anyway.
