This is a clip of a concert in which people can see Blake Shelton and Michael Buble perform together, which is going to be a rare opportunity indeed. At the beginning of the video, viewers can see some witty and personal banter between the two of them, which can make the video seem that much more endearing.
Famous people are always going to see more real when anything like that happens. However, the banter is soon completed, and the two of them progress to their actual performances. They both deliver fantastic vocal performances. However, the way the performance is staged still gives everything a more casual feel and look to it, which helps preserve the fun that the two performers had at the beginning of the video. Even people who have never heard of these two performers would probably like to watch this video and SHARE it on Facebook, and their fans would definitely like it.
