Sir Roger Daltrey fears he won't make it to the end of The Who tour because he has "the potential to get really ill".
The band has been on the road this year and they are due to kick off their final North American tour in Florida on August 16, but Daltrey fears health issues could scupper the dates as he could have problems with his voice and he also worries about damage from a previous battle with meningitis which has left him struggling to perform in warmer climates.
