We've had #CatsAgainstBrexit and the excellently named Operation Croissant, but the latest pro-Europe campaign is using the power of song. At 5.30pm today, a crowd of people will be coming together to sing in sweet, sweet harmony for a European sing-in flashmob in Leicester Square. If you can't make it tonight, they'll also be doing their thing at 8am tomorrow at City Hall and at 12:30pm on the South Bank.
Whether you've got the voice of an angel or can't sing a note in tune, the organisers are asking people to get involved and don their most colourful outfits, make placards and help promote all that's good about the EU. They're also providing song sheets for some EU-themed tunes, including that well-known hit 'EU Are My Sunshine'.
