I have bought both these collections, and although I personally think this collection is slightly better than the opening ceremony, which has more instrumental pieces and none of the music used to show, to showcase the changing music through the decades is on the discs anywhere apart from Mike Oldfeild's Tubular bells re-working. Now the closing cerermony has most of the music from the event. Where us British have an advantage over the rest of the world is we have the best and most memorable music, with The beatles, Stones, Who and Kinks. Although most artists obviosly mimed on the night, all recorded special versions of the songs and these are the ones collected together here. The Beatles are representes with Russall Brand attempting to do I am the Walrus, it's not fantastic but its not dreadful either. John Lennon gets Imagine with some delightful children sining at the beginning, Lennon is still relevant today as he was then and I am glad he was included. Madness give us Our house, Annie lennox gives us Little Bird and prooves her voice is still up to it unlike some others who should throw in the towel(both these are rerecorded and not the original versions). The Spice girls give a quick medley of Wannabe and spice up your life(a song I really hate).Fredie Mercury gets the crowd going with a bit of Day 'o' and then Queen perfom 'We will rock you' with jesse J which works ok. Muse are on top form doing survival and the Kiser Chiefs do a good version of pinball wizzard. However the Who themselves proove they still can do it and perform a fantasic thrio of songs ending in My Generation. Take That sing Rule the world a good choice, George Michael performed two tracks Freedom and his knew song White Light,but only White light is on this collection, a lot was said in the press of Michael performing a knew song, personally if it was as good as his older stuff I would not have minded so I'll leave that there. Kate Bush provided a remix version of running up that hill and that song is still brilliant as is David Bowie's Fashion. Pink Floyd had to be represented somewhere and with Nick Mason teaming up with Ed Sherman and Mike Rutherford, they covered at least two major aritsit from the past with Wish you were here. In the end this is a suvenior for the 2012 Olympic, something I originally beleived was a waste of time and money, but by the time I watched the opening show, I suddenly became proud again to be british and changed my mind. So if you purchase this don't expect the best versions in the world and like all complantions not every track will delight everyone, but listen like I did and think we still have the best artists anywhere. Now all we need to do is pull out of eurovision but that another story.
