If you've always wanted to watch gibbons by sunset or observe meerkats in a duskish hue, now's your chance. Head on over to ZSL London Zoo tonight for a rare evening event. The zoo will remain open until 10pm, with live music and other entertainment including a 'stunning light and dance finale' (hopefully, but probably not, involving monkeys). You'll also be able to see the three Galapagos tortoises recently acquired by the zoo, and experience the horror of not being able to get the theme tune to One Foot In The Grave out of your head. Tickets are around £17 if booked online.
