Black Friday have been playing Celtic folk-punk since 2005, drawing on Irish and Cornish roots. Led by captain Tom, the six-piece mix their own songs with Celtic tunes and a few Pogues and Flogging Molly covers. They have played Glastonbury, Boomtown and Electric Picnic, recorded a live session at the BBC’s Maida Vale, and hold a Guinness World Record for 30 gigs in 12 hours.
