Being ill is understandable, and I believe lack of sleep/rest after one point would apply as well. The body needs it’s rest.
But given that ‘Hamlet’ is technically his (real) baby? Dropping out would look very bad not to mention that it would shine a glaring light on the ShamWow. This is a fauxmance that is slowly destroying him. I think he would be able to weather one with the right ‘co-star’ but SH is the problem here. I don’t think this is going to end well…and I’m not even talking about the critics.
The impression I got from the general response to his CBE? Is that they are going to take pleasure in ripping him a new one.
