It seems as though Elbow will be supporting Muse on their upcoming tour:
"Rumours are circulating that ESP may support Grandaddy on the European leg of their upcoming tour, after Elbow pulled out to support Muse instead. Grandaddy are due to tour, amongst other countries, France, Germany and Belgium between the 14th November and the 5th December. It would be the perfect time for ESP as their own UK tour finishes 2 days prior to this in London. More news as we hear it."
