Isn't the cheese just a rebus?
I played around with the photo for a couple minutes and I think that's one
of those off-brand stands that were around in the late Eighties/ early
Nineties, which is about the vintage of those keyboards. The boards are
definitely consumer instruments, you can see the little icons of drums on
the "fallboard" of the top instrument, and both of them have built-in
speakers, I'd go with Yamaha for the top one and Casio or Technics for the
bottom one. Looks like a hotel banquet room too, check out the carpet and
the chairs. Bet this gig was boring as all hell.
