Well I tell you something - now this is in depth analysis from s floor singer of many years standing ((theres never quite enough room for me a seat).

There comes a magic moment somewhere between the second and third verse (the first verse - natural politenes gets in the way, the second verse - you may notice a slight rictus of displeasure float across the features of several men in fisherman's smocks) HOWEVER!

The start of the third verse is generally when you finally realise you are about as welcome as a fart in a space suit - any other place on the earth's surface would be more hospitable, and you should have a strategic withdrawal planned.

A line that sometimes works for me is - 'Parts of the next line contain adult material....... and as we are before the watershed, I must abandon you to your more simple minded pleasures. Keep it folk! That's what i say! Good night...... and f--k off!'
