Hatch, Kirby, Lloyd, Kelly and McEwen all have thir strengths, and are all pretty good, when used at the right time. Blythe, less so. Let's face it, listening to any commentator for 6 hours, day after day, we're going to find things that annoy us, peak Richie Benaud excepted.
Weirdly, Hatch's Lancashire accent, and it is pretty thick, has come out at times this Giro. There was one instance where he may have thought he was off air, when it was full on. He does actually try to tone it down during commentary, in an attempt to make more palatable.
