Born on the remote island of Los Hingos and raised by a two-headed snake, Champagne Pete & Dave Wee Froth became aware of their calling for good-time idiot cock rock by accident. Whilst in the forest hunting for truffles they fell into an ancient well. Stranded from their mother they survived on rainwater and ants, passing the time by fashioning a crude guitar from the remnants of a palm tree and guitar-string like cobwebs (a bit convenient, but it makes the story work). Using the acoustics of the well, Dave Wee Froth honed his vocals. Before long, they were playing and singing songs about the island, the great Mount Tuk-Tuk and their mother.
After several months they were found by a group of English explorers. They were rescued, taken back to England and introduced to clothes. The head explorer, Randolph Forsyth-Venkman quickly discovered their musical ability and purchased Champagne Pete's first ever guitar (Dave Wee Froth received nothing and even now, borrows a microphone from that bloke in the park who can eat his own face).
The rest, as they say, is history. The Hinge have become the biggest band in the world*, headlining major festivals** and being credited by both Van Halen & Whitesnake as "the guys who we look up to".***
So there you go. That's their story. That's how it happened. Or you could believe the shocking rumour that they are just two guys who met in a pub and started jamming. Your choice.
* That bit isn't true
** Nor is that bit
***Yeah, they didn't say that at all
