Betchadupa was a New Zealand pop/rock group, formed in Auckland, New Zealand, in 1997. The band featured Liam Finn, Chris Garland, Joe Bramley, and Matt Eccles.
Betchadupa (originally called Lazy Boy – the name change followed threatened legal action from the chair company of the same name) had its origins when Liam and Matt met whilst their families were on holidays in New Zealand. Their first song, written when both boys were 11, was called 'Gee This Sounds Good, I Can't Believe We Wrote It'. Their unique name was lifted from the text of a Polish-American's T-shirt that declared "You Betchadupa I'm Polish", dupa being the casual Polish word for arse.
The band based themselves in London, UK, after spending much of 2004 in Melbourne, Australia. The band have been on hiatus while Liam has undertaken a solo career. It is uncertain if the band will ever reform.
