John Lennon amazed the world with 'Imagine', his song of hope and peace for the human race. It has been covered by everyone from Elton John to Pink.

I ran across this video of Lady Gaga covering 'Imagine' for the opening games of the European Games, which are like the Olympics for European teams only. It is an absolutely gorgeous rendition, and one that not only stays true to the original, but adds Gaga's own signature touch.
