Andy's "travel" pieces have usually been excellent, he's a good journalist as well as having a vast knowledge of music. I found his 2005 Turkmenistan programme to be another fascinating item.
I appreciate that a presenter's voice can be very off-putting - there are certain other R3 people whose voices annoy me but fortunately they're not on every week so I can listen to those programmes selectively.
Of the 3 presenters that R3 have been using regularly on the Monday night programme since AK disappeared last May - Lucy Duran, Charlie Gillett and Mary Ann Kennedy - I would venture that MAK has been the best, though her programmes haven't really got the breadth of music which was present with AK.
