I listen to Classic FM and I am very glad he has left ! I found him to be very annoying these days. Yes he once was a decent DJ but whereas Tony Blackburn is just as good as he used to be I feel Simon Bates is very tired in the way that he presents. Just my opinion ! but I always switched off when he came on - and DJs like Mark Forest - Myleene - etc at Classic FM are far more suited to the relaxing nature of that station.
Good luck to him though and the idea of Smooth Radio is quite a good one with the aging hippie generations

and Radio 2 being more for the 25 - 50 age group.
