I was fairly hopeful at the start with some nice traditional-sounding instruments and a beat but then it all went wrong. A sort of Greek rap intersperses with the chorus line. There's not a great deal going for this. It is about refugees, apparently, which may be a good move and get some sympathy votes from the politically see-me-I-am-correct types but I doubt if that'll be enough.
Greece usually do well with support from all quarters so they'll get some way up the board but whether this will get off the right hand side is not guaranteed. The video is not that attractive. See it here.
