It's certainly got the Sonoton/Studio One sound to it, though I don't recognise the actual track in question - it could also be the Manfred Minnich Orchestra.
Yes, Manfred Minnich (and his aliases) is a consideration a well. I have listened to the following LPs:
Manfred Minnich:Tanz-Express
Europhon Record ELP 541
Mitternachtsparty - actually found only two songs of this LP on You Tube - is it on that one?
Studio One 3 -

https://www.youtube.com/watch?v=ZP3LlrHp4CURomantic Guitar (actually not listened to, because it says "guitar")
David Summerfield:Music for Lovers
Happy Harlequin
George Winters:Lights On
Programme Production No. 6
Programme Production No. 18
But was unable not spot the track in question. I might be missing some of his LPs. For instance, I have not found so much from Werner Bild.
And I was unable to find George Winters "Holiday Dreams". Is it on that one?
I still tend more to Gerhard Narholz just because of how the strings have been arranged. But Gerhard Narholz has released so much more that I need some help to nail down the choices...
