Whether it's 2am and you're at a wedding or 3am in sweaty Coppers, when C'est La Vie comes on all bets are off.
It's your responsibility as an Irish person to jump around the dance floor like a maniac, whacking out your best Irish dancing impressions.
B*Witched lead singer Keavy Lynch got married last week and the same rules applied for her big day.
Best finale to a wedding ever! 👰 Congrats again @Keavylynch You looked beautiful #cestlevie #somerset @BWitchedreunion @edelelynch 👠👠👠pic.twitter.com/8RlrWfjAgZ

Keavy, and fellow band mate and sister Edele, pulled it out of the bag and the wedding dress gives the whole performance a kind of fairy tale feeling, which, let's face it, you wouldn't get in Coppers.
