What is the name of the band who played at Glastonbury an accoustic set for a BBC interview about 7pm Sunday?

Outside in front of a Tee Pee, and the horse. One Blonde one Brunette,
backed up by two guys on accoustic guitars. One of the girl singers
also had an accoustic guitar. I think I heard the BBC interviews say
they were managed by cold play or something like that.
