Re. his talking over guests - it's a fine line between getting some good responses, and also providing a humourous backdrop to the interview as well - some manage the balance better than others.
I always used to wonder what his Capital breakfast Show was like, living outside London, I never heard it. having heard him on Radio Two, I realise i wasn't missing anything! On the 'Allinson Scale' - a '10' being as boring and pointless as Richard Allinson - tarrent is a good eight, with occasional gusts of nine - he is well tedious!
