I've heard the name but never heard him on the (what?) air.
Is he an angler or just a broadcaster.?.
He is (was) a match angler. Fished big matches in the '70s and '80s, I think? He even won one once, I think? He worked in the tackle trade for years. He writes a weekly column for Angling Times. He did a few VHS fishing videos in the past. He used to present "Fisherman's Blues" Radio show on Talksport until recently but they reduced the hours etc so he packed it in. It was on at about 6am on Sundays so not to many people knew about it.
I only came across him as a presenter when I got Sky a few years ago. He presents the weekly show (Tight Lines) on Sky Sports. Despite some of my posts in this thread I actually think he does a great job. Despite his image from his Angling Times column (grumpy old man) he actually seems like a jolly cheeky chappy on TV.
I like the show. It is one hour long. It's on once a week. It's the only up to date 'as live' weekly fishing show in the UK. Keith presents it and you have a different guest each week. There are two 10 minute fishing films. These are new and up to date films (most are available for free on the Sky website). The guest then shows a few of their rigs etc and they have a chat about their specific speciality in angling.
The problem is that he has verbal diarrhoea and just cannot let his guests talk through and explain their methods! He IS very knowledgable. But he acts like he knows everything about every discipline in angling. He has various 'theories' and 'ideas' that he insists on repeating week after week instead of just letting his guest (who is an expert in their particular field) explain their own methods.
This is nothing personal. Just my perception of him.
