Question Author
Many thanks for your assistance everyone.
It turns out wires were crossed - the PR wanted me to set up the meeting, which is fine, he simply didn't make that clear in his mails to me.
He got really snotty and told me if I didn't sort it, he would 'have to get another writer'.
Apart from the fact that the choice of writer is not his call to make, it's the sort of nonsense I have to put up with on a regular basis to get hooked up with musicians, who with virtually no exceptions, are charm and professionalism personified, dealing with their press officers who are very often miserable, rude, and difficult.
A writer's life for me tra-la tra la .......
