Other shows have managed it. I can't imagine the presence of a show in Leeds or Plymouth will have much of an impact on London audiences, or vice versa. It all depends on whether the producers of the London production think it has a future there, and whether everyone involved thinks they can save a worthwhile amount of money by sending parts of the London production on tour instead of building a new production from scratch.
Sure, many other shows have managed it - I just don't see Spamalot doing so. A Monty Python musical, even in Britain, only has a limited audience in the first place, and I can't see having it in London and out on tour being successful. Spamalot has been somewhat struggling at the Palace for a few months now and business is slowing into the summer, a time when theatres struggle anyway. I would have thought it would be better to go out on a high in London with Alan Dale etc. and launch an Autumn national tour using the London set etc.
In addition, Lloyd Webber is desperately in need of some RUT's for Phantom of Manhatten, Oliver! (assuming it doesn't go to a DMT - possibly Novello? [though I reckon that would be too small if they're using Anthony Ward's 1994 set again]) and then for Priscilla and Sister Act, all of which RUG is (or is supposedly) involved in. The Palladium may well open up, as might Drury Lane though.
And as for why David Ian's biog is in the Jersey Boys programme, that's exactly the same question I asked myself when I saw it. He was obviously involved in the process of negotiating its London run - possibly theatres etc. as Howard Panter and the Ambassador Theatre Group are also quoted as a producer?!
