I do not understand why it is necessary when re opening a pub to re name it.
The failings of the pub, usually by it's previous owners, may be numerous but I've never heard of someone boycotting a pub, or the pub failing just because of it's name. In fact I'll go as far as to say that in retrospect re naming a pub is, 90% of the time, the kiss of death, in some cases some pubs have had 3 or more names as they've transformed over the years and the new names very rarely cut it, the mucky duck is a classic example now the Pig and Pump WHY!!! the Phoenix another.
Take for example the Welbeck {now the Hidden Knight} why re name a pub that's probably been on the site with the original name for millennia, it's not the pubs names fault, that's the only thing that for certain isn't to blame for it's failure.
Yes over the years certain pubs got a reputation, some really bad reputations but that's only down to clientele or the standard of beer served or maybe bad management or a culmination of any or all of those.
So why reopen as Hidden Knight what on earth was wrong with the Welbeck?
