NE-YO says it broke his heart to let fans down when he walked off stage mid-show at his Manchester gig last week, and he hasnâ€™t cried so hard for years.
The R&B singer updated his blog to say he blamed the meltdown on a sinus infection and not having had a holiday for a few years.
He says his family, music and fans are the most important things in his life and it â€œliterally broke his heart to tell 12 000 of the people responsible for making (him) who he is that he could not performâ€.
â€œIâ€™ve never had to stop a show, never dreamed Iâ€™d ever have to,â€ he wrote. â€œI cried harder than I have in a very long time with no shame whatsoever.
He says he knew something was up almost immediately.
â€œFrom the first song I knew something was wrong. I shoulda stopped there, but I come from a school where no matter what, the show must go on.
â€œIt wasnâ€™t until about four songs in that I came to the painful realisation that my voice was done, literally nothing left, and that I would have to stop the show.â€
On his website, he tells Manchester fans: â€œI love you and and I thank you for being so understanding and supportiveâ€, promising they â€œwill receive the show (they) deservedâ€.
But he also has a message for those who â€œquestion his manhoodâ€ for getting emotional.
â€œIf you knew that the people you cared for the most you had to disappoint and it was your fault… and this didnâ€™t spark some kind of emotional outbreak within you…then with no shame, Iâ€™ll say you are truly a stronger man.â€
Ne-Yo struggled to sing on stage for more than half an hour at the MEN Arena in Manchester last Thursday.
BBC Manchester presenter Karen Gabay was at the concert and said Ne-Yo looked like he had a â€œreally bad feverâ€.
She says Ne-Yo started his gig 30 minutes late and announced that he wasnâ€™t feeling well quite early on.
â€œEven after the second song, for a man who is normally so cool, he was sweating.
â€œHe was doing a Michael Jackson tribute and you could see that he was actually struggling to finish every musical phrase. He kept asking the audience to bear with him.
â€œMy friend also noticed that his songs had been shortened.â€
Gabay says Ne-Yo then went off for a â€œvery long breakâ€ before he came back on stage in â€œfloods of tearsâ€.
â€œHe absolutely couldnâ€™t hold tears back â€” the crowd were applauding him and he couldnâ€™t bring himself to speak.
â€œThen he said heâ€™d never had to do this before â€” heâ€™d never not been able to finish a show â€” he said it though tears, it was unbelievable.â€
The R&B singer was able to perform at his other UK gigs, in Liverpool on Friday and Newcastle and London over the weekend. â€” BBCOnline
