Australian musician Daniel Buccheri performed an epic mash-up of contemporary and classic songs for his brother Adrian at his Melbourne wedding to Sarah last month.
The pair exchanged vows on March 29th and the performance has racked up nearly half a million views on You Tube.
The newlyweds are visibly moved and wipe away tears during the touching performance and there wasn't a dry eye in the house by the time his six minute set finished and he toasted the happy couple.
He adjusted personal lyrics to Sam Smith, Usher, The Police and the Backstreet Boys to narrate his relationship with his brother and the new chapter in his life.
“When you moved out of home, I thought, ‘thank the Lord, I won’t be missing you’,” Mr Buccheri sang.
"Then you were gone with a special girl. I thought you were dead, never saw you again.
“Although you met on the internet, I know this love is true. It is enough to let the dogs on your expensive rug.”
Bucchari said he was shocked by the response to his speech, saying: “I didn’t realise that when I wrote it but I think it’s a bit too much of a rollercoaster for some people.
“I just wrote it as a speech but as I recorded it to listen back to it I started to realise that it had potential.”
"I forgot that everybody else was in the room. It was one of those moments where it was just me, Adrian and Sarah.”
