Copyright

The Saturdays have copyright over their song, Ladykiller. Copyright is "the exclusive and assignable legal right, given to the originator for a fixed number of years, to print, publish, perform, film, or record literary, artistic, or musical material." It's a form of intellectual property, like a trademark. Due to copyright, we are unable to do a video to their song without permission. 

The consequences of copyright infringement in the UK:

"While there are many consequences of breaking copyright laws, the most common include monetary fines, loss of property, loss of freedom, or loss of employment. Typically, copyright law violations involve someone attempting to profit from, distribute, or claim material to which they have no rights. In some countries, copyright infringement — the use of copyrighted material without permission or the right of ownership — could carry the penalty of criminal and civil punishment if the copyright owner should choose to file a claim and take the guilty party to court"

We have attempted to contact The Saturdays in order to ask permission that we are allowed to use their song in our music video for copyright reasons. For this, we made a fan account and tweeted The Saturdays joint official account in hope that we get a reply.
