Magical Mystery Tour

A quotation (in ODQ), starting on the  appropriate side of the grid, runs clockwise around the perimeter. The other unclued entries (one of two words, one of three words), will show solvers the event being described, interrupted by some disposals. The original author of the quotation, found in anagrams in symmetrical answers, must be highlighted, as must the name in anagram form of the poet who wrote about the ‘event’.

A first prize of £100, three prizes of £25 and six further prizes of The Penguin Book Quiz: From The Very Hungry Caterpillar to Ulysses by James Walton will be awarded for the first correct solutions opened. The first four winners will each also receive a bottle of champagne. Entries by 20 January to: Christmas Crossword, The Spectator, 22 Old Queen Street, London SW1H 9HP.
Please include a phone number. This is to arrange delivery if you win champagne.
