Just a few minutes ago I've seen (and heard of course) a brand new cover of Hallelujah in Polish, sung live by Ryszard Rynkowski (one of the well known Polish pop singers). There was a special concert in Warsaw, marking the 26th anniversary of the election of Polish Pope John Paul II.
I must say I was positively surprised - this is one of the best covers in Polish I've ever heard.
I hope they will repeat this concert in a few days, so I'll be able to videotape it this time.
