What’s with the show title, I Am the Wilrus? It’s not much more than a rather dodgy pun, of course but it somehow sums up the eccentric style of Australian comedian Wil Anderson, who - like the song itself - seems to flit from one random association to the next, yet leaves you feeling strangely satisfied by the end.

Of course, such seemingly effortless freeform riffing is always meticulously prepared, but Anderson papers over the cracks with a cheerful, goofy, energetic presence. A star of television and radio in his homeland, he plays to the large amount of his countrymen and women who have come to see him, although the indigenous cracks aren’t enough to alienate non-Aussies. Australian humour, he says, is a scrawled ‘I fucked your mother’ on a toilet door, with ‘dad, you’re drunk, please go home’ added below.

Yet, matey early riffs on his country and childhood subtly win the crowd over, so when Anderson tackles subjects like religion and racism - often somewhat bluntly - in the same amiable style, he’s already won our trust. It’s a sharp and pacey torrent of jokes, but delivered with a skill that’s worth savouring. (David Pollock)
