Adele refused to scrap a concert despite illness because she aims to "do every single one" of her shows after previous tour cancellations.
The Hello singer, who has a troubled history with touring, told the audience during a show in Birmingham, England on Saturday (02Apr16) that she was frightened she would have to cancel because she was battling through inflammation on her chest during her Friday night concert (01Apr16).
However, she was determined to keep all her dates and refused an offer to cancel the Friday night show and she took medication so she was feeling better in time for the Saturday performance.
"I had some steroids, right, to take the inflammation down and I was so frightened I wasn't going to be able to do tonight's show and I did. I woke up and I felt fine. I'm so relieved," she tells the crowd, according to fan footage posted on Twitter.
She says members of her team said to her "maybe you shouldn't do it" but fans had already begun arriving at the Genting Arena, so she pushed through the show.
"I know back in the past I used to cancel shows," she explains. "I never cancelled anything for no reason, but my main goal in life over the next year is to do every single one of my shows."
Adele has scrapped concerts on both of her previous tours. In 2008, she dropped dates to spend more time with her then-boyfriend, and in 2011, some shows were postponed when she got a chest infection. In October, 2011 she cancelled the remaining dates on the North American leg of her tour after she suffered a vocal cord haemorrhage, which required surgery.
Before her Adele Live tour was announced, she lied and told the press she was unsure about embarking on a worldwide trek. She told BBC Radio 1, "I would love to go on tour and I would love to think I have it in me to do one of those global tours. Whether I do or not I don't know."
Adele's current tour is her biggest trek to date. She is performing 22-dates in the U.K. and Ireland alone, including eight shows at London's 02 Arena, before moving onto mainland Europe and North America.
