The frontwoman of Florence + the MachineFlorence Welch, recently visited Hospice Austin’s Christopher House in Texas to surprise a 15-year-old fan. 

Welch dropped by because a fan who bought tickets to a Florence + the Machine concert was prevented from attending due to her illness. While there, Welch gave a private acoustic performance joined by guitarist Rob Ackroyd. In the footage shown above (via Vulture), Welch sang “Shake It Out” from her sophomore album Ceremonials. To Welch’s surprise, a fan also sings as back up. While singing, Welch interjects, “Such a good harmony!”

Welch also sang “Dog Days Are Over,” from the Florence + the Machine debut record Lungs. The room is full with family and friends clapping and singing along.
