The 71-year-old rocker pulled out of a charity gig and dates on The Who's 50th anniversary tour last year (15) after he was struck down with the potentially deadly illness.
Roger revealed he spent four weeks in hospital as he battled the condition, and he feared he was going to die.
"I crawled into the hospital on my hands and knees," he told Britain's The Sun newspaper in December (15). "I started talking gobbledygook (nonsense), I couldn't get anyone's name right and my legs went all funny. I virtually stopped working... It was touch and go there for a few days. I've never known pain like it.
"I know it sounds weird but an incredible peace came over me, which I can still tap into now... I guess when you face adversity you learn something and you gain something.
"It was touch and go. But out of all that I came to terms with my own mortality... I was ready to go, and if I had to go I would have gone with a smile on my face."
Luckily for him, Daltrey has since recovered and he performed in Detroit, Michigan on Saturday (27Feb16) as part of The Who Hits 50! tour. During the show, he thanked the "nice people who supported me last year", adding, "We never gave up."
