Speaking as, what is now, one of a rare breed I would like to endorse what my friend Watson says. I produce and present a folk programme on BBC Radio Shropshire, Stoke and BBC Hereford and Worcester. It is broadcast live on a Sunday night between 8pm and 10pm. I am local, approachable, flexible - I answer my emails (mostly!) and I promote local gigs and talent - as well as (inter)nationally known famous folkies. I try to cram as much into two hours as I can. I also put my money where my mouth is and I can be found at local sessions - joining in with live music & song.
I'm hanging on in there ... and so is Mick Peat on Derby.
So, let's try to keep folk on local radio ... and by all means get more on national radio ... but - use your local folk programme - if you've still got one left. Radio is driven by audience figures - and if no-one is listening - why broadcast it? It's no good singing about how good the old one is when it's all gone, is it?
