Tel Aviv, Israel( CNN) Always camp, often cheesy and occasionally political, the Eurovision Song Contest rarely passes off without some kind of controversy.
Last year, the contest — which pits singers and bands from different countries against each other in a week-long competition culminating in a spectacular live final — was won by a quirky vocalist called Netta Barzilai, representing Israel( despite the title, entries are not restricted to European nations ).
And because the winning nation gets to host the following year's contest, this year the Eurovision caravan has pitched up in Tel Aviv.
