Well said Pip.

I quit going to one very well known Folk group because every singalong was hogged by half a dozen regulars who though they were better than everyone else.

At one session, one of these hogs actually said "you have to push in here", I replied "If I wanted to push in I would have joined a Rugby club"

The only people who like to "damn well step up" are those arrogant sods who think that they are the best ever and don't give a shit if shy people never get a turn.
