For decades film-makers and playwrights have been imagining what would happen if their greatest heroes met.

Only last year Alan Bennett's play The Habit of Truth dreamed up an encounter between poet WH Auden and composer Benjamin Britten, while the 1985 Nicolas Roeg film Insignificance had an meeting between characters that closely resembled Marilyn Monroe and Albert Einstein¹.

Of course, there is evidence that, outside the bounds of fiction, many of the greatest figures in history not only rubbed shoulders but also became friends. A recent book, Peter Pan's First XI by Kevin Telfer, tells the tantalising real-life story of the cricket team put together by JM Barrie at the start of the 20th Century that included such literary giants as Sherlock Holmes creator Sir Arthur Conan Doyle, PG Wodehouse and Winnie the Pooh mastermind AA Milne among its number. And it is said that Conan Doyle made the acquaintance of Oscar Wilde through the group, and that their meeting inspired not only Wilde to pen The Picture of Dorian Gray but Conan Doyle to pursue his then putative career as a writer.

Earlier in the year we asked who would be on the guest list for your fantasy dinner parties, but now we'd like you to go one stage further...

• Think of your two greatest heroes from history, the arts or entertainment. What do you think would happen if they met? Would they get on? What do you think they would talk about?

• Do you think their encounters would generate any great collaborations? Could you see Handel and Paul McCartney writing a symphony together, Salvador Dali and Damian Hirst knocking out an installation or two, or Oscar Wilde and Quentin Crisp trading quips?

• Or do you suspect they wouldn't get on at all? Would it be a disaster?

• Or are there any lesser known folk from history that you'd like to see get an audience with a globally renowned personage? And how much would you like to eavesdrop?

Over to you...
