Florence + The Machine is back at No. 1 in the chart with her latest single.
The success of the song is partly down to Florence's many festival appearances over the summer but mostly due to the huge Calvin Harris remix.
The song is taken from Florence Welch's 2011, 'Ceremonials', which also brought us the singles 'Shake It Out' and 'No Light, No Light'.
