Tove Lo live remixes Telephone with Do What U Want
And Carly Rae Jepsen's Run Away with me on piano!
And Carly sings Cyndi Lauper's Time After Time!
Why, Tegan and Sara have covered Time After Time too!
Those crazy ladies also covered Umbrella!
Which brings us back to.... KELLY CLARKSON, singing Stay!
