Friends of the newlyweds decided to shake up the church ceremony with a rendition of ABBA's "The Way Old Friends Do"
One of Love Actually's most memorable scenes involves the wedding of Juliet (Keira Knightley) and Peter (Chiwetel Ejiofor). Peter's best man Mark, who is secretly in love with Juliet, hijacks the celebration by organizing a musical outburst.
If you've never seen the scene, with singing by the late, great Lynden David Hall, the below is required viewing.
Inspired, friends and family of Bernie Gavin and Cian O'Leary took over the couple's ceremony with a rendition of ABBA's "The Way Old Friends Do". They were joined by singers Joe McNally and John Bourke.
Gradually making their way to the altar in the County Westmeath church, they then broke into Liverpool anthem "You'll Never Walk Alone" - a nod to the groom, a huge soccer fan.
Planning your wedding? Best make sure you extend the invite to some musical guests. You never know!
