Problem: On 30 October 2009, May wrote a fanclub letter on his website stating that Queen had no intentions to tour in 2010 but that there was a possibility of a performance. He was quoted as saying, "The greatest debate, though, is always about when we will next play together as Queen. At the moment, in spite of the many rumours that are out there, we do not have plans to tour in 2010. The good news, though, is that Roger and I have a much closer mutual understanding these days—privately and professionally ... and all ideas are carefully considered. Music is never far away from us. As I write, there is an important one-off performance on offer, in the USA, and it remains to be decided whether we will take up this particular challenge. Every day, doors seem to open, and every day, we interact, perhaps more than ever before, with the world outside. It is a time of exciting transition in Rock music and in 'The Business'. It's good that the pulse still beats". On 15 November 2009, May and Taylor performed "Bohemian Rhapsody" live on the British TV show The X Factor alongside the finalists.
Which member of Queen wrote a letter to fans in 2009 regarding touring for 2010?
