I am sorry Brian Mathew is not returning, I do like him, and his stopping appears a matter of controversy.
I would be fine if Mike Read did the show - I wouldn't want Johnny Walker because, although he retains his wonderful radio voice, he has the personality of a paper clip, so I would prefer he does not expand his current output.
No danger of Travis - he left under a cloud, which has darkened after his sexual assault cases.
Craig Charles is dreadful - why on earth he gets airtime is a mystery to me.
I do think it's time that Tony Blackburn got Pick Of The Pops back - I think the fact that Paul Gambaccini plays only generic jingles, no personalised ones, hints that he thinks he is holding the show until the genius of TB returns.
