When Prince appeared on the box the other day, my mum expressed her approval.

I asked why, and without hesitation she offered: ‘He respected and promoted women’. It struck me initially as a weird reason but upon further reflection seemed spot-on.

He wrote many songs from a female perspective in the early ’80s, many of which have never seen the light of day.

Then there was Vanity/Apollonia 6 – dubious acts for some, but without too much moral adjustment you could interpret them as ‘women reclaiming their right to enjoy sex’.

Then there were Prince’s striking collaborations with a variety of strong, independent characters: Ingrid Chavez, Sheila E, Sheena Easton, Dale Bozzio, Mavis Staples, Cat Glover, Elisa Fiorillo, Bonnie Raitt, Nona Hendryx, Wendy & Lisa, Susan Rogers and Peggy McCreary.

How many other male ‘pop’ icons can boast such a coterie of female cohorts?

Then there was Jill Jones. With hindsight, her 1987 debut album, released on Prince’s Paisley Park Records, is one of the great missed opportunities of his career, and its standout song ‘Violet Blue’ particularly demonstrates why.

The album started in the summer of 1983 during the filming of ‘Purple Rain’ (featuring Jill’s less-than-stellar cameo), when she replaced Prince’s guide vocal on ‘Mia Bocca’. Sadly he didn’t find time to resume work on the record until over two years later.

Consequently, it’s very uneven, with some decent material (‘For Love’, ‘My Man’) mixed in with middling Prince outtakes, covers and B-sides (‘All Day, All Night’, ‘G-Spot’, ‘With You’) and undone by rushed arrangements and drastic changes in tone.

‘Violet Blue’, recorded at LA’s Sunset Sound in October 1986, was the last song put down for the album. Quite simply, it shows what the record could have been, and, frankly, how much Prince (and Jill) had developed between 1983 and 1986.

The vocal intro and accordion breakdown are two cases in point, not to mention the interesting chord progression and superb horn (Eric Leeds) and string (Clare Fischer) arrangements. Jill delivers a knockout vocal too, even throwing in a neat little Nancy Wilson impression via Dinah Washington.

Sadly the Jill Jones album sank without trace. She has recorded intermittently since, contributing a great guest vocal on Ryuichi Sakamoto’s ‘You Do Me’ and playing low-key gigs. She’s always a refreshing presence.
