Charltons is a unique melting pot of businessmen, students, vocal aspirants and snooker hacks who share a common love of drinking and singing from 3am onwards.

1. You can only find Charltons when you’re intoxicated

2. The worst song of the night will undoubtedly be some guy’s version of Bohemian Rhapsody

3. The gin and tonic tastes like cough syrup

4. The karaoke doesn't sound any better from the pool tables
