I think it's sad this sound is not appreciated any more. There is so much 'retro', vintage and nostalgia, why not regarding old-fashioned bigband sounds? But it tends to be used for documentaries sometimes.
I assumed at least people over 75 would still be interested in this music, but it seems not to have a strong pull effect in rest homes either.
BTW, anyway, if my Integra version manages to sound as dated as the early 60s, I achieved what I intended, as it is hard to make a synthesizer really sound like dated music. It just doesn't seem to be a profitable business to compile something like this, if there's maybe 1 Kaempfert fan per rest home ;-)
