The Internet overflowed with “Tweet Is Murder” jokes earlier this week, after it seemed Morrissey had at last joined Twitter. His alleged first tweet (“Hello. Testing. 1, 2, 3. Planet Earth, are you there? One can only hope…”) seemed to be in voice, at least, and the Mozzer quickly attracted a quarter of a million followers on the social networking service. (Still, subsequent tweets make the account seem fairly… business-related. As in “come to this show, pre-order the record,” etc.) There’s only one problem: Morrissey says it’s not him.
