As a quick response -
The reason Joey Barton is interviewed is because of his history with City. The interview does not celebrate Barton. We asked him about the key incidents in his City career - and when facing City - and it's for the audience to make of it what they want. The incident with Dabo, while not in this week's edit, will be featured; we haven't shied away from asking him about the bad stuff because we'd be failing if we did.
It's also worth pointing out that it's seven minutes in a 65-minute show (and the second part will be the same) - if he's really that unpalatable, then you can skip through it. However, as much as you may disagree with what he says, how he says it, or what he thinks or stands for, we'd urge you to listen and comment on it. It'd be boring if we only interviewed people who had nice things to say all the time.
