The Conchords have landed

There's a woman in America with a photo of Jemaine Clement's lips in her wallet.

The picture of Clement, who with Bret McKenzie are the musical comedy duo Flight of the Conchords, shares pride of place alongside snapshots of her two daughters.

While the Conchords are not hugely popular in the United States, they do attract a few hardcore fans like her.

And now they are making a 12-part show for American network HBO their popularity is set to soar. More on that TV series later.

But first, the pair have made a documentary, Flight Of The Conchords - A Texan Odyssey, about their time at the South By Southwest (SXSW) music festival in Austin, Texas, this year.

It's in this documentary we meet Jemaine-obsessed Deidra. "We stay in touch with her. She's cool," says McKenzie.

We also meet Lisa who is very keen to get to get to know McKenzie better. "I think I'm in heaven because I'm standing next to you," she says, looking adoringly into his eyes.

"Yeah, I'm not quite sure what to say," says McKenzie.

Some fans travelled for days to see them perform in Austin. "We haven't had actual stalkers, but they're just keen and eager fans who are excited to meet us, which we don't have a problem with.

"I don't want anyone to get the wrong idea. We don't walk the streets of America being chased by adoring women throwing their underwear at us."

The idea for the documentary was suggested by producer Gemma Gracewood who had been to the festival a number of times.

SXSW is one of the biggest music industry festivals in the world and the place to be if you want to be the next big thing.

The White Stripes, Franz Ferdinand and Norah Jones were discovered there.

"You hear the festival being talked about in industry circles and between bands, but I don't think many people have even heard of it," says McKenzie.

"It's not a public festival, but it's important and a lot of Kiwi bands [including the Datsuns and the Mint Chicks] have been to it and I think it's cool for New Zealand to see what's going on over there. Plus, what we were also keen on doing, was showing New Zealand a snapshot of what we are up to overseas."

He says the show ended up being a "documentary, mockumentary, travel show".

"It doesn't quite know what it is," he laughs.
