Found it (first result for "machine gun lyrics mistaken sms police"): http://www.theregister.co.uk/2004/06/03/text_punk/ http://www.theregister.co.uk/2004/06/03/text_punk/ "Devine, who plays in a Clash tribute band in his spare time, had sent a message containing lyrics from The Clash's Tommy Gun to his lead singer who had forgotten the words to the song. According to The Sun, the message read: "How about this for Tommy Gun? OK - SO LET'S AGREE ABOUT THE PRICE AND MAKE IT ONE JET AIRLINER AND TEN PRISONERS" The arrest has prompted speculation about how the message was intercepted. Police maintain that Devine's message went astray. They say he actually sent it to a woman in Bristol by mistake and it was she who alerted police to the content. However, The Sun also quotes Chris Dobson, a terrorism expert, as saying that the interception clearly shows that GCHQ is monitoring all vocal and textual mobile phone traffic."
