Thank you all for your replies, as Ankou says it is the funeral director paging, have since found this on the web,
‘Paging away’ is when the funeral director leads the cortege on foot and is done as the hearse begins to move away for the first time, as the cortege passes a place of particular meaning to the deceased, or on arrival at the cemetery or crematorium. This tradition probably originates from when horse-drawn hearses would send a page ahead of the cortege to stop other coaches which would stop to give the coffin and mourners precedence as a mark of respect.
Thanks
John
