I saw Dylan Moran live last night, amazingly he came to Tasmania. (Even he couldn't figure out why) The show was excellent and he was in top form, intelligent yet childish, satirical yet truthful. He spoke about politics, the environment, the medical profession and children among other whimsical off topic subjects. The show was sold out, as I understand it to be in most cities where he is performing! If you can though I would highly recommend checking him out!
Hopefully this show (obviously not the local one, but the tour in general) will be released on DVD at some point, but it will not compare to seeing him live!
