It's not often you see Sarah Jessica Parker, Viggo Mortensen and R2-D2 in the same room, particularly for a comedy show. The bad news is the "stars" who have turned out for Long and Nightingale are cardboard cutouts. The good news is I'd swear there's a smile on Parker's horse-like face by the end of the show.
This relaxed double-header opens with Nightingale's riff on xenophobia, a workshop complete with flipchart and Magic Markers. He's trying to sell "alternative racism" as a way to deflect the real thing. Let's not hate people we know and have to deal with, he says, but instead those we rarely encounter. What's more, let's do it for a transparently daft reason. Get the idea? The audience do: they suggest we should hate the Belgians. The reason? "They took the German flag and turned it on its side." That'll do, Nightingale says.
How do you out-silly that? Long, a smiley, bumbly soul whose bad haircut is a fitting match for Nightingale's foul sideburns, gives us a rare insight into the social lives of Paul McCartney and his friends Axel Rose and Bob Dylan. What does Macca sings as he brings in dessert? Sounds like the Bond theme tune Live and Let Die? That's right: Lemon Meringue Pie! Perhaps you had to be there.
