I'm struggling too.. I have 'cram' for congest,? and I thought 'yob' was for the clue 'yahoo'? What do you have and any others for the left side of puzzle? 1a and 1d would give me a start.
jillypotter, filmfan, eccles. A nightmare I agree but many thanks for your help. Think I've finished but is the 'old joke' clue answer 'chestnut'? Rings a bell somewhere in my mind....
