If I'm right about this, when ever Rovers/Burnley or Preston Go up or down a coffin goes in or out of the ground and gets blessed - just an excuse to have a few beers I think.
Its nowt to do with Burnley. For every Rovers or Preston relegation the 'dead' club is laid to rest in a pub cellar in Bamber Bridge and 'raised' when promoted. Very old tradition with procession and service!
