Hi Squeezy, I live in Chelmsford too. Go to LanFranc's site. The Blackmore club meets in Writtle 1st Thursday of the month. It is a very well attended, friendly, welcoming club. Got shloads of talent. I love it.

In Margaretting at the Red Lion there is a free sing/play around session every 2nd Thursday. Very well attended. Amazing talent.

In Billericay at the Rising Sun there is a pay (tiny amount at the door) floor spot session in the function room out back every last Thursday of the month.   Some of the same people attend Blackmore and Margaretting. Only been once so far, but plan to return.

I did not know about the Woolpack... Must check this out.
