This is a very un-tedious subject and I also had the same reaction as you upon hearing that very interview, my mouth opened and an almost silent "wow" was produced. That Johnstone fellow is a very clear speaker and I was happy to listening to him,
The bit nearing the end of the broadcast wherupon Mr Johnstone sighs as he speaks then goes on to state something like "as someone with some knowledge about this, I cannot say I am comfortable that further revelations will not come out"! Putting the double negative aside that was quite a statement and If fans of that dank and fowl club had brains, they would be worried. I do have a brain and Im rather chuffed!
Indeed im giggling into my cremola foam as I type.
