“I can’t sing any of my songs in the key I originally recorded them in. I don’t know how those kids on ‘The X Factor’ do it – it’s crazy how they hit the high notes. Adele gave me a great tip if I ever tour my songs – before hitting the high notes I’ll turn the microphone on the audience and let them do it,” Sia told “The Graham Norton Show”, reports femalefirst.co.uk.
Sia also shared that her hit track, “Alive”, was originally written for Adele’s new album “25”, but it didn’t make the final cut.
She said that it was rejected by singer Rihanna.
“We were writing it for her new album but it didn’t fit with the other tracks so she rejected it. I sent it to Rihanna’s people and they rejected it, but in the meantime everyone said I should do it myself.”
