Apparently someone who is a fan of MP and works at the hospital posted in the comments:
I'm a doctor that works at the Whittington hospital in london. I wasn't working in the a&e department tonight however I am sorry to hear of your plight. As much as I'd jump at the opportunity to help you if I actually was on call tonight, please try to understand. Us healthcare professionals don't want anyone to wait or suffer at all, however we encounter life threatening conditions every hour, sometimes every minute, that stop us from seeing others that may be slightly less unwell, as quickly as we'd like. The NHS is under-financed, understaffed, overworked. We do have to economise our resources.
With all the respect I have for you, it hurts when one of my idols insults an organisation I work very hard for. Waiting sucks, I know, but dying patients suck even more.
I sincerely hope you feel better and that the show goes well tonight. Gutted to be missing out due to a prior engagement. Rock on though, love the new Neal Morse album.
