Oh yes, dust off the Silver Knight to rotate in sync with the Te Deum, and see if John Benson is still drawing breath to utter those immortal worRAB "And now, Live from Norwich - " (which are not strictly correct,,,he never said "live" on Sale of the Century). They could have it at Carrow Road and get Saint Delia of Canary to do the green room nibbles. I'm sure the Hotel Wroxham, or even the King's Arms in Ludham would do a good room deal!
Failing that there's always the Little Theatre at Sheringham but they'd have to run a tight ship in terms of the show timings in order to make the last train back to Norwich.
