Tegan and Sara are so amazingly talented and i love love love their songs. This is one of my favorites and i wanted to find a live version of them singing to show how amazing they are live. Tegan and Sara are sisters that write there own original songs and they sing beautiful harmonies together. If you like what you hear i recommend listening to some of their other songs like 'Walking with a Ghost', 'Nineteen', and 'Call it Off'.
