It seems that J will not in fact be playing music on Friday, but will instead be reading a selection of his favourite poetry.
What other reason can there be for these gems found on the back of the ticket for Friday :-
"Mobile phones and pagers must be turned off, and watches silenced, before entering the auditorium". Watches silenced ?????? Are they worried that an electric watch that bleeps hourly will drown out JM&TF ?
"Latecomers will not be admitted until a suitable break in the performance". (Presumably after the main set and whilst J has a slash before the encore starts !)
Let’s hope J reads us some Pam Ayres.
