An Irish bride and groom in County Monaghan were brought to tears as their wedding guests surprised them with a stunning cover of "Stand By Me." 

In one of the best and sweetest surprise wedding performances we've ever seen, a group of friends and family surprised newlyweds Shane and Rachel McNally during their wedding ceremony with a cover of "Stand By Me." 

The idea first came to their friend, Hannah O'Brien, when she realized that their wedding, held at St. Joseph's Church in Carrickmacross, Co. Monaghan, would have many talented singers and musicians among the guests.

"I realized that there were going to be plenty of singers and musicians attending the wedding and saw the opportunity to do something special for the happy couple who love music," she told the Irish Mirror. 

With help from the band Sterling Blue, friends and family held secret rehearsals for five weeks before the wedding.

After the ceremony, the singers began standing up from among the church pews before all coming together at the front of the church to serenade the happy couple. 

The video shows Rachel and Shane both wiping back tears as they listen to their loved ones of all ages singing.
