Best man's unusual wedding speech stuns bride and groom

A best man's moving musical speech at his brother's wedding has had more than 200,000 views since it was uploaded on Friday.

Australian musician Daniel Buccheri paired original lyrics he wrote for his older brother Adrian and new wife Sarah to the tunes of well-known pop songs.

The 25-year-old surprised the newlyweds with the six-minute medley at their wedding in Melbourne last month.

"I was so humbled to be my brother's best man, so I decided to prepare a little surprise for him and his new wife on their wedding day," Buccheri explained on his YouTube channel.

The newlyweds are seen both laughing and crying throughout the tribute, with the brothers embracing warmly at the end of the song.

The songs Buccheri used in his speech:

• Stay With Me - Sam Smith

• Every Breath You Take - The Police

• Ignition - R. Kelly

• Can You Feel The Love Tonight - Elton John (The Lion King)

• Hey Soul Sister - Train

• As Long As You Love Me - Backstreet Boys

• Stay With Me - Sam Smith
