The Scottish singer recently filmed the promo for the band's new single, Detroit City, in Michigan but they decided against going through official channels in a bid to keep costs down.
Spiteri admits the whole shoot in Detroit was carried out "guerilla-style" and one scene ended in disaster when they attempted to film outside the Motown Records building.
She tells Britain's Daily Record newspaper, "It was made very clear at Motown that you are not allowed to film or take photographs... It's very strict... We thought we would get some footage out front, but as I stepped on to the grounds, the security man was on to us right away. He was well mannered, but when we told him it was personal footage, he asked why we had a camera crew. He explained that they ask you to apply to film and that there is a cost attached. We got chased."
The star carried out a number of similar stunts during the two-day shoot, including filming on top of a multi-storey parking lot, and Spiteri admits they did a good job keeping their tiny budget in check.
She says, "You do it guerilla-style now and try to capture moments... (Getting permits is) far too boring. Maybe the rebels in us are coming out in our old age. The truth is, you apply and wait. There wasn't time. In America they are very strict about stuff like that. You can get a ticket for crossing the road. It's a cheaper way of making a video. We made so many videos over the years and some we paid a helluva (sic) lot of money to make that are s**t. We used a good camera crew, but didn't need to pay for scripts and directors."
