It's been a tough week for Foo Fighters.
Dave Grohl broke his leg onstage in Gothenburg, with the band subsequently forced to postpone a flurry of shows.
Pulling out of dates in Murrayfield and Wembley, Foo Fighters were also advised by doctors to pull out of their Glastonbury slot.
Florence & The Machine have been drafted in as replacements, with Florence Welch posting a quick Instagram message to fans.
Stating she is "thrilled" to be involved, the singer then commiserated with Dave Grohl and posted a picture of the genial rock frontman with the group.
We are so sorry to hear that the Foo Fighters have had to pull out of Glastonbury, we met Dave Grohl a few years back and he was the nicest guy ever. And let me and @isamachine hang out with him, even though we were clearly very drunk, and I had no eyebrows… We are honoured to have been asked to step in, and we hope we will be able to give you as good a Friday night as the Foo's would have… Sending all our love and well wishes to Dave, See you in the field FATM.
