Classic nerves. He's not used to being a LIVE broadcaster. I've done public speaking for years and you can tell - speaking faster, more animated, higher pitch... just nerves.
We thought that about McCrory the longer the night went on more red he got but also more funny he's a brilliant pundit!!
Haye is clearly not well. You can see it in his comeback interviews with IFL. Mumbling, slurring, looking pasty and drawn in his face. You can't blame it on nerves as been in and around broadcasting for years. He's also clearly skint (credit cards declined, cheques bouncing, selling the ring from his gym). This isn't going to end well for him.
