Lead singer and guitarist Jack arrives for our interview in typical rock star fashion - late and hungover.
I must admit I was worried they were going to fall asleep halfway through a question, but my worries were unfounded because as soon as they sat down with me they were upbeat, talkative and refreshingly honest.
They can obviously handle hangovers a lot better than I can.
Formed only a few months ago, all the members of Jack Green and the Band of Thieves are local.
Jack Green, 24, grew up in Hayes while brothers Danny Gardner, 20, double bass player, and guitarist Jo Gardner, 22, were raised in Uxbridge, and drummer Alex Craig, 23, is from Twickenham.
It is Harrow that brought the band together. It is where they met, socialise and continue to develop their music.
Jack says: "The Harrow music scene is experiencing a second wind. A couple of years ago it was a lot more vibrant and there were a lot of acts that made it big.
"For a period of time then it all went quiet, but it's coming back. The Trinity bar is responsible for a lot of that."
Ah yes, Trinity - the hub of the music scene in Harrow. It made me feel all warm inside when Jack described the bar as a community, a place where everybody knows and supports each other. You don't usually associate London life with a feeling of community.
Jack is the backbone of the band. He started out by himself and got the band together. He also writes and coproduces the songs, and has been involved in music from a young age, teaching himself to play the guitar.
He says: "If you take music lessons you tend to play like a robot - a standard industry way of playing. I don't think my style is like that, it's not very conventional."
The band's influences are an eclectic mix. Jack draws inspiration from Bob Dylan and Gogol Bordello, who play European gypsy folk music.
He is also heavily influenced by literature and authors such as John Wilmott and Charles Dickens.
Danny takes inspiration from Elvis and rockabilly music, and sports a quiff to show just that.
Jo is more into up to date indie music and are influenced by bands such as Radiohead.
Finally Alex is classically trained so favours more complex music.
Phew... you would imagine that with a mix like that their sound would be all over the place and couldn't possibly fit together. Well you would be wrong. The band's first single Man on Mars is an up-tempo, fresh and funky track.
They have been likened to Dexy's Midnight Runners and this connection is plain to see to anybody who listens to this song. There is a buzz around this band and this single and it is easy to get drawn in. Their infectious beats can get anyone dancing and they are instantly likable.
The band's self-titled first album will be out February or March and I predict these guys could go a long way.
