There's every chance that you've seen the Abba musical Mamma Mia - at the moment it's playing in 16 different countries and has made $1.6 billion by basically shoe-horning as many Abba songs as it can into a confusing story that nobody cares about.
And stop looking so pleased with yourself if you've escaped the brain-pummelling sensation of watching Mamma Mia in a theatre, because your escape routes are currently being blocked off - there's going to be a movie made of Mamma Mia especially for people who want to pay half their weekly wages to watch some people who aren't Abba singing a load of over-familiar Abba songs while sitting on a sticky chair surrounded by wankers who won't stop throwing popcorn or talking to their friends on their mobiles all the effing time. Anyway, Meryl Streep's going to be in the Mamma Mia film, so that's something.
