Watch: Best man sings his speech at his brother's wedding and had everyone in tears

It can be a tough process to write a great best man speech, but it must also be even more difficult to sing it.

Singer-songwriter Daniel Buccheri decided to do just that recently at his brother's wedding, where he was the best man and wanted to give a speech to remember to the bride and groom.

Buccheri covers a number of popular songs in the medley that he performed (including office favourite here at entertainment.ie HQ, Train's 'Hey Soul Sister' which is second only in our list to Train's 'Drops of Jupiter'), although he changed the lyrics to talk about the wedding, the good times that he and his brother shared growing up, as well as a joke or two about him being under the thumb now that he's married. As with all good speeches, it ends on a touching and emotional note, and you can see that his brother is struggling to not shed a tear or two at the end.
