Beverley Knight said her studio collaboration with Chaka Khan was "deafening".

The soul singer had always wanted to record with the veteran 'I Feel For You' hitmaker, and when they finally recorded 'Soul Survivor', the results were very loud.

Beverley, 36, told BANG Showbiz: "When we get together singing, my god, it's like something unleashed.

"It was very loud in the studio. The tones of our voices are not similar but the range and, in terms of the noise we make, it's quite similar. So it was quite deafening when we were both in there."

Beverley also explained how she had originally set out to write a song for Tina Turner, but liked it so much she couldn't let it go.

She added: "I originally wrote the song in a studio session with Guy Chambers - it was meant for Tina Turner, I wasn't even going to have it. But the when I finished it I was like, I'm not giving this to Tina Turner, I'm keeping it for myself.

"And I called It 'Soul Survivor' and that is Chaka Khan's whole life, as well as my own story on a smaller scale. And she loved it, and totally got it and that was that.

"This was the first thing I've written where I've thought, 'yes, that's me and Chaka'."

'Soul Survivor', from the album '100 Per Cent' is released on March 8 and Beverley is on tour throughout the UK in April.
