Just listened. I think that’s a bit harsh tbh and he’ll get used to doing more interviews. No need for media training IMO. The interviewer’s (James?) sound was much higher / closer so it’s more a case making sure he’s miked up properly next time I reckon. At one point the passing train’s almost as loud as his speech. If I stuck my phone speaker to my ear I could hear everything he said, but only at full volume. He’s just a quiet speaker, but articulate enough.
