The girl band who sang in the nude… and the other antics some of our biggest pop stars thought they’d kept secret – until now

When a once-towering pop group is on the verge of splitting up, the words that pass from the lips of the band members are usually safe, unemotional, sterile. Well, they would be. There’s still music to be sold. Listen, we all still love each other. So what if our best friend wants to leave the band in order to go solo We remain focused on our music. Roll up, roll up and buy the new CD!

It’s only years later, when the record sales have evaporated, that the stars can honestly explain how it felt when things turned sour. And then the truth starts tumbling out.

Listen to Siobhan Fahey, original member of Bananarama, who had more UK chart hits than any other girl band before or since.

Life inside the group was grim after the first happy years, says Fahey now. ‘You go from being best friends to really irritating each other. And then not wanting to be around each other… I felt lonely and lost and friendless and really unhappy.’

Fahey walked out after realising she was unable to ‘stand on stage with people I felt resentment for’. Her account of life behind the scenes in pop is revealed in I’m In A Girl Group – one of three riveting BBC2 documentaries about the music industry (the other two are I’m In A Boy Band, and I’m A Pop Star).

The programme-makers have spoken to dozens of stars from yesteryear, and there are plenty of colourful and surprising revelations along the way.

we had was the five of us. And it just wasn’t the same any more.’ On a
doleful note, she reflects, ‘It’s a bit sad when you’ve achieved your
dream and it’s not what it’s cracked up to be.’

there are plenty of lighter moments in the documentaries too. Did you
know that Susanna Hoffs, of US girl band the Bangles, recorded the
vocals for their smash hit Eternal Flame in the nude The band’s
producer had told Hoffs he had just finished working with Olivia
Newton-John, and that she’d got her best vocal takes when she sang

‘I thought, “Wow,
that sounds really cool. I want to try that.” And, sure enough, they’d
say, “OK, time to sing,” and they’d listen for the sound of the clothes
dropping to the floor.’ It was only later that the truth was revealed to
the Bangles singer: the stuff about Olivia Newton-John had been a total
fabrication – ‘and I fell for it’.

It’s also amusing to hear how Bananarama caused a headache at a Top Of
The Pops recording by hiding in a laundry basket when they were meant to
be on stage, and how Rick Astley, never a fashion icon, was so
unprepared when he was first asked to appear on the all-important TV
show that he had to stop off at a menswear shop in Manchester on his way
to the studios in London.

wasn’t a successful shopping trip. The jacket he picked up was several
sizes too big and made him look like a six-year-old dressing up in
Daddy’s suit. Astley recalls thinking, ‘Surely it doesn’t happen like
this Surely someone says, “We’re going to have a meeting. What’s this
fellow going to wear on Top Of The Pops”’

Instead, he says, he was simply told, ‘There’s the microphone. You
shuffle about like a good ’un.’ Not that Astley can complain. In 1987,
Never Gonna Give You Up went to number one in 25 countries – and the
unlikely pop star went on to sell a total of 40 million records.

fact, Astley got off lightly. Three years earlier, Nik Kershaw – he of
the 1984 smash hit Wouldn’t It Be Good – was given the ‘assistance’ of a
record-industry stylist before his Top Of The Pops debut. The result A

More attractive he may be, but a little less distinctive perhaps. A few
weeks ago, Kershaw revealed that his toddler was having trouble telling
him apart from another ageing pop star. ‘Theo, my 18-month-old son,’
Kershaw wrote on Twitter, ‘just pointed to a picture of @howardjones and
said “Daddy”.’
