Seriously. Just buy 'dieselking.com', and have it redirect to whatever one website you have your content on. There is no way on earth, you self-important wankers, I am going to check anyone of those urls, let alone all three.
Or, even, get dieselking.com, and put an actual website on it. You know, with a bit of self-respect.
And hey, If dieselking.com is not available, maybe that's a good sign that you should have a different band name. You idiot.
