If you look at the track list of the CD, most are buzzing immediately the odd song from the impromptu sing or one or the other line, is the Holiday originally by Madonna, The Power Of Love by Huey Lewis, Wild Boys of Duran Duran, etc. The songs were chosen to be 100% classic. The cover versions of songs, and the songs on this CD, vocally rarely, if ever reach the class of originals should be clear to everyone. But they are mostly quite well done and provide instrumental and how they are sung, quite the flair of the originals. Very few songs seem not quite perfect. One it has in the singing actors so here and there to do with quite talented people and Leona Lewis, who also mixes together here, is known as a great singer of songs like Bleeding Love. The CD you can listen to absolutely, if you can live with the fact that the overall result is not quite enough to cover songs so great scores like Mamma Mia or Rock of Ages zoom. Generally, I'd say 3.5 stars would be fair, but with nostalgia bonus that's enough for four.
