Re: music on funeral?
Nice idea 
Well maybe the village was just happy that the person died .. I can understand that feeling.
On a serious note, it looks like one continuous scene but except for the first part where the camera moved from dancing boy and music band to empty coffin box, there was no indication that later part of the video had dancing going on in the background except for the background music (which could easily be added through any movie maker software)
In any case, this is not barlevism as some of the comments of youtube are suggesting.
