KD Lang performed one of the best songs and raised the most amount of money during a song during the inter Fire Fight Australia Concert on Sunday. It was also good to see how relaxed she was as you can see in the video she is barefooted throughout her song. She sang one of the hardest and most emotional songs – KD Lang sang the song ‘Hallelujah‘. It was such an amazing version of the song that I have heard. You have to watch the video below, it was just so amazing.
