OKAY, politicians. Just stop it.

Stop using really good songs for your conferences, rallies, whatever.. In the same way that many a fine tune has been ruined by John Lewis at Christmas time, your ‘borrowing’ of classic pop hits is getting on our nerves.

Take poor ABBA. They must be fuming this week.

A few years ago, the Swedish supergroup’s male half - Benny Andersson and Bjorn Ulvaeus – were furious with the Danish People’s Party (DF) for using their hit Mamma Mia at rallies.

(The youth wing of the party had changed the lyrics of the song to Mamma Pia, in honour of their then leader Pia Kjaersgaard.)

Messrs Andersson and Ulvaeus threatened to sue, and the party agreed to stop using the song.

No wonder they were angry. Who would want far-right, anti-immigration politicians bopping along to a song, previously loved by practically everyone in the world, and now doomed forever to be a reminder of intolerance and a right wing agenda?

Enter, stage left, Theresa May.

In what someone presumably thought would be a totes hilar moment at the Conservative Party Conference, she made her entrance to Dancing Queen, jigging about with as much rhythm and elegance as someone who has been stung by a wasp.

As if the cast of Mamma Mia hadn’t already done enough damage.

The PM is not the first politician to commandeer chart hits for their own purposes. And ABBA are not the only ones to object.

Calvin Harris was not pleased when Theresa May entered the stage to the his collaboration with Rihanna, ‘This Is What You Came For’ in 2017, and Adele was upset with Donald Trump when Rolling in the Deep was used during his campaign in 2016.

So, all of you, just give it a rest.

Anyway, evidence of music being put to a much better use was all around us last week as Evening Times Scotswoman of the Year Sally Magnusson and her charity Playlist for Life helped to launch the BBC’s Music Memories website.

This idea, inspired by a growing body of research on the beneficial effects of music in helping those with dementia, is brilliant.

Users can create their own playlist from snippets of around 1800 tracks, including the most popular songs from the last 100 years and TV and Radio theme tunes, and are invited to share their top tunes to help others.

You only have to spend five minutes on the site to understand how incredibly clever this is.

Within a few tracks, I was transported right back to my old living room, 1980-something, Dallas and Cagney and Lacey on the telly; to the heartbreak and happy dancing of high school discos (thanks, Boy George and Whitney); to the simultaneously exhausting and joyful first few days in hospital with my new born sons (Westlife and The Darkness, Adele and The Feeling…).

Music is powerful. It lifts you up, brings you down, keeps you sane, helps you escape.

And thanks to organisations like Playlist for life, we now know music reaches parts of the damaged brain in ways other forms of communication does not.

This is vital work. It brings people with dementia back to their families, back to themselves. Watching it in action is awe-inspiring.

It is unlikely anyone will ever say THAT about politicians, dancing along to the best of ABBA.
