Can't speak for Ed but from memory I think he said he was baffled by the Jack business, Terry too.
MK making a point of mentioning Jack at Mandela made the whole thing even more weird, especially when, let's face facts, very few people in the 5 billion or whatever worldwide audience would have had any idea who he was.
Again, RIP Jack. I never met the man but I had a few interactions on here and social media and he was always great.
