No-one likes hiccups during their big day, especially the bride and groom. Just after exchanging their wedding vowels, the bride and groom got a pleasant surprise that they were not expecting. Neil and Tricia Swan were surprised to hear that the priest began singing and then he was joined by a guest in the audience. The bride’s friends put together a flash mob and sang ‘How Great Thou Art’ for this special occasion. Towards the end of the song, the bride was left in tears, as she was overwhelmed with the whole flash mob.
