So, alongside the report from the BBC Trust which was heartening about 6Music there was a separate report (well, a connected one) into Radio 2. This one, in short, agreed with complaints of commercial radio that Radio 2 isn't doing enough to serve older listeners.
Naturally, commercial radio doesn't really give a honk on the traffic helicopter's horn about whether older people find stuff on radio which they like or not. If commercial radio was bothered about that, it would make programmes for people over the age of ten. But it does feel that the more time Radio 2 is tending to the 65+ age group, the less time it will be playing newer music, and thus the less competition there will be for Heart.
This does sort-of fall down a bit in the assumption that you lose interest in new music as you get older - as if it vanishes with your hair.
Still, the BBC Trust has bought the argument:
Radio 2's under-35 audience had "grown significantly over the last 10 years, albeit from a low base, but since 2004 this growth has stabilised", the trust report added, with 82% of Radio 2's listeners now aged over 35 and an average audience age of 50.
But the report warned that the number of over-65 and "in particular" over-75 listeners had fallen. "Radio 2 should investigate the reasons for the decline" and "consider whether its range of music continues to meet this audience's expectations", the trust concluded.
There is a possibility that, since people who are 75 now would have been 18 just as rock and roll was bursting out, and so might be more likely to listen to the Beatles and Stones of Gold networks than be found gathering round a bunch of old 78s. Radio 2 might have a lower percentage of over 75 year-olds than they had a decade ago because over 75 year-olds are more confident at moving between media outlets and less easy to pigeonhole than their parents were.
