What do you get if you put 30 plus girlfriends, who also happen to be Abba fans, in a cinema to watch the summer's big blockbuster?
The answer: utter chaos, dancing in the aisles, singing along with the cast and just a few quiet tears.
Having fun was The Name of the Game at the Saar Cineplex this week as a group of Dancing Queens gathered, popcorn in hands, for a showing of Mamma Mia! The Movie - a film slammed by the critics but loved, loved, loved by the public who, when asked do you want to see a movie based around all your favourite Abba songs, chorused I do I do I do, I do I do, in their scores.
The get-together was organised by Super Trouper Cherry Chapman, a Mamma Mia! veteran, who's seen the film four, or is it five? times.
She said: "I absolutely love Mamma Mia!, there's no sex (well maybe just a hint), no violence, no bad language - just good, old fashioned entertainment. You get to sing-along to all the songs and you leave the cinema with a feel-good sensation inside.
"I decided to organise a get together for just a few girlfriends but it seems to have snowballed - that's the power of text. Some of the women here have seen the film before, some are Mamma Mia virgins and I'm sure they're going to love it."
Her pal Barbie Williams added: "It's a lovely, fun film but you need your tissues, particularly those who have daughters. I went to see it with my daughter and she said 'I'm not even going to look at you' because she knew that, at a certain point, I would be blubbing."
Barbie's also been to the stage show, which she feels might be slightly better than the film, and others of the gang have seen the movie in various settings including an outdoor showing for 3,000 people in England, a country not known for its Summer Night Cities ... now that's what I call devotion.
Inside the movie theatre, the audience was made up almost exclusively of women of all ages - most of them friends of Cherry.
The lights went down, the screen lit up and we were off on a cinematic odyssey to Greece via the songs of the much-loved Eurovision Song Contest winners.
Far from One Man, One Woman, this is the tale of one woman and three men; Pierce Brosnan, Colin Firth and the other one - OK his name's Stellan Skarsgard but let's face it sharing screen time with these two heartthrobs was never going to be easy.
I'm not giving away any state secrets when I reveal that the storyline involves Sophie (Amanda Seyfried), as the daughter of Donna, played magnificently by Meryl Streep.
The pair live on a picture perfect Greek island and, a ridiculously young-looking, Sophie, about to get married, Has a Dream to find the father she has never known.
Unbeknownst to Donna she sends an SOS to the three possible culprits inviting them to the wedding and, Just Like That, they are on their way.
Before long it emerges Sophie's mother most definitely doesn't know what she has been up to and The Visitors are thinking, 'it's One of Us ... but which one?'
Much confusion ensues and, though the plot has been slated as thin - to the point of transparency, simply being a vehicle to string together a bunch of Abba hits - there are laugh-out-loud slapstick moments aplenty and big dance numbers the like of which you rarely see in today's films.
The use in song and dance scenes of, what appear to be, genuine Greek islanders (if they're not, they bear a striking resemblance to the lovely Greek mamas, yayas (grannies) and fishermen I recall from living there) is, in my view, a touch of genius adding extra comedy value.
Sophie and Sky, great choice of name, I recall lots of my friends around that time saddling their kids with similarly unfortunate monikers, are just about as saccharine sweet as young lovers can possibly be.
So it's good that they're balanced by the richness of talent in Streep and her sidekicks, Julie Walters and Christine Baranski, as unlikely a former Rock 'n' Roll Band as you're likely to find.
If you didn't know Streep was a trained singer you would easily spot it in the this film which is just as well as Pierce Brosnan's caterwalling is excrutiating - all right, perhaps I exaggerate slightly, but James Bond just should not be allowed to make that sort of noise.
However, by the end of the film, the whole audience would have forgiven him anything such is the feel-good power of this movie.
I'm not going to spoil it by giving away the ending, though that doesn't seem to matter to those devoted fans who seem more than willing to say Gimme! Gimme! Gimme! (another cinema ticket).
Sufficed to say that from I Have a Dream to Mamma Mia! it seemed the whole audience knew every word.
Dancing Queen had one woman out of her seat and strutting her stuff around the cinema and the scene in which Donna sings Slipping Through My Fingers to her daughter, brought more than a few tears to their Angeleyes.
By the final credits, when Streep, in full rock chick mode demanded 'Do you want one more?' all the women, and even a few of the cinema staff, were on their feet, clapping, singing along and dancing in the aisles and in front of the screen.
Critics be damned, their message to Bjorn and Benny is clear. Thank you for the Music.
