Sarah, 39, will release the song, entitled Wear It Like A Crown, on the streaming service at midnight.

The tune was recorded by Sarah ten years ago and rediscovered by Sarah while researching her autobiography Hear Me Out.

Sarah and her team wanted to make the song available to their fans, the money went to The Christie.

After Hear Me Out was released last week, Girls’ Aloud’s 2004 track of the same name returned to the charts.

It was a new entry at number 28 in the official Big Top 40 at the weekend.

The news comes after it was revealed that all five members of Girls Aloud had a secret reunion – the first time together in eight years.

Sarah said the band got back together shortly after going public over their cancer diagnosis last summer.

She was joined by Cheryl (37), Nadine Coyle (35), Kimberley Walsh (39) and Nicola Roberts (35) for an overnight stay in the classy members’ club Soho Farmhouse in Oxfordshire.

And Sarah reveals in her autobiography Hear Me Out, published tomorrow, that she was afraid to see her after treatment for breast cancer.

She writes: “The steroids I was taking made me look bloated and I had lost my eyelashes from chemotherapy.

“It’s not that I thought they didn’t understand or judge, of course. It’s just that when we were together as a group, part of our business was glamor.

“As a band we all had our own styles and looks, but Girls Aloud had a sexuality and glamor that I just couldn’t rise to at the time.”

During their reunion, they re-watched their 2006 E4 documentary show Girls Aloud: Off The Record. Sarah said, “We were all so different back then. We had a kind of sweet naivete.

“Watching Off the Record laughed a lot and huddled even more, but I have to say I watched lovingly. “You only miss that when it’s gone,” I said to the girls.

Cheryl said, “When we all met at the Soho Farmhouse, there were no tears. Actually, that’s not entirely true; There were tears, but they were more from laughter than sadness.
