LULU has said she will perform the David Bowie collaboration The Man Who Sold The World on her upcoming tour.

Bowie co-produced Lulu's version of the title track from his third studio album with musician Mick Ronson.

"I can't not sing The Man Who Sold The World. I can't not do that song," she said.

The son was released as a single in 1974 and peaked at number three, giving Lulu an unlikely top five hit after 1969's Boom Bang-A-Bang.

"That was a very big important point in my career and I had a personal relationship, albeit for a moment," she recalled of her time with the late pop star.

"Like everyone of his generation, I feel sad for him, but I feel really sad, because I'm a woman, for his wife and for his family.

"From what I can tell, I think they're coping with it beautifully and I think he came to terms with his death quite admirably."

Lulu, 67, has teamed with The Military Wives Choirs for new single Cry.

Due for release on February 26, all proceeds will be donated to The Military Wives Choir Foundation.

The charity, for service personnel and their families, supports women in the British military community.

When asked how she became involved with the Military Wives, Lulu discussed her struggle with post traumatic stress disorder (PTSD).

"Several years ago I was diagnosed with having PTSD. I have been anxious all my life," she said.

"I was told, your childhood was a battleground. You kind of lived in a warzone as a child. My upbringing set me up in maybe not a good way in some ways, but set me up in other ways in a very resilient way.

"My parents coped as well as they coped. Bottom line, I feel I can relate to the soldiers and their families and that's why I'm doing this song. I wanted to help in some small way."

To support the single's release, Lulu will perform Cry with a different Military Wives Choir at each of her 34 UK tour dates throughout March and April. It includes dates in Glenrothes, Motherwell, Inverness, Aberdeen and Perth.
