Many thanks to all,
I'd really like to listen to those TDK C90's, that sounds exactly what I'm looking for. Just the raw radio commentary, warts n all.

My memory is fading a fair bit so can anyone give me a timeline for which commentators were where? and when?
ie when was Tommy Robb based at Balacraine?
When did Geoff Cannel start and finish at Ballaugh?
Is there a book on all of this?

I like the idea of contacting Fred Clarke and other forums.
cheers
