All of the other suggestions that were given already are very good and one other thing that you might want to try is finding out who the major concert promoters are in London and then checking their websites on a regular basis. They will probably have an newsletter you can subscribe to and get the dates as soon as they are released. And the tried and true method… entertainment sections in major papers (most have a newsletter you can subscribe to.
