Here's another event to consider.
If you are at a loose end this weekend, you could do worse than to come along to the Battle of Ideas at The Barbican which takes place this Saturday and Sunday. The BoI is an annual festival of free thinking and debate which has now entrenched itself as a must-visit for anyone with an interest in such things.
If you're unfamiliar with the event, it's where around 2,500 people converge on the Barbican to hear discussion on an array of subjects by speakers from all over the world. I've written about the good, the average and the panto baddies in previous years (see here and here, for example, and I can also highly recommend my good friend Tom's blog from 2012 here), so I will be trotting up there again on Saturday (at least) this time around.
There is a lot to be interested in, such as slots discussing questions like Statute overload: are there too many laws? and Free-range parenting: reckless or responsible?, as well as Snowdon debating 'Boozy Britain' with public health types.
Oh yeah, and there's also a session entitled Planet of the Vapes: why is there a war on e-cigarettes? at midday on Saturday featuring some bird called Lorien from Cornwall (who I've written about before). That might attract some interest too, you never know.
That is just a small selection of the large array of subjects being covered so, if you've got nothing planned this weekend, get yourself a ticket while they're still available and I'll hopefully see you there. And for beer after, of course.
