Yes, that's right. many concerts cancelled over the coming days.
All West End theatres are closed tonight too. It would seem the low life scum are succeeding in terrorising the people of London.
It's not that they are succeeding. It's that key people have not been able to get to work, or get home afterwards. So stages & sets haven't been finished.
Also, while I am all for "business as usual" approach, I think it is equally important to heed official requests to not travel, as at times like this there are usually very good reasons for them to ask. Like shortage of key workers, or resources requiring re-direction towards rescue or other effort.
Apparently the cellphone networks went out today not because the authorities wanted to stop panic, but because the emergency services needed them.
As for travelling in London tomorrow, I suspect it won't be easy until they have got the trains back into the right places etc.
