Wait, what?!
Wikipedia time... Mira Awad is actually the Israeli Arab, I always thought she was the Jewish one and Noa was the Arab! I very much doubt Mira would have taken part in that back then (it would have been a big deal for a start) and she doesn't look like anyone on stage whereas Noa looks a bit like both of the backing singers! Her Wiki page says nothing about her being part of it though.
I say I like it for the political side because the Israeli broadcaster effectively cut all relations with, ahem, Ping Pong after they found out they were going to waving Syrian flags around on stage as a sign of peace (don't know if anyone in Syria was particularly moved by their message!). It was far too late for the broadcaster to withdraw the band as they presumably would have got a massive fine given that it was the week of the contest.
