This Castleblayney lad SANG his bride up the aisle: Internet MELTS

When it comes to Irish weddings, there's a tried-and-tested formula which most couples tend to stick to.

The ceremony itself is a sweet, but sedate affair generally accompanied by a church organist or soloist while the reception (and the days after) signal unbridled divilment.

Turning the notion that you must stick to a paint-by-numbers routine on its head, one groom decided to forego the standard wedding march, and chose instead to SING his wife-to-be up the aisle.

In a move that has really hit Facebook users in the feels today, Charlene Casey shared footage of her baby brother serenading her new sister-in-law as she made her way up the aisle.

"My little brother sang his beautiful new wife up the aisle yesterday with their friends Ryan on guitar & Jennifer on harmony," Charlene wrote. "It was the perfect start to a memorable day."

The upload has been flooded with comments from people who can't get enough of this couple's first step into married life, with one writing: "Fair play to him. Dunno how she held it together. I'm in floods and don't even know them!!"

Ladies, prepare yourselves for this one.
