I found a few more references to GG in pop culture
About 2 years back an insurance company up in Germany used the Aria from the Goldbergs as background music for one of their ads. I cant remember the name of the insurance company or wether they used a GG recording. If my memory starts to kick back in I will let you know.
Legendary german "band" Einstürzende Neubauten have a track on their latest CD called "I kissed Glenn Gould".
Those of us who grew up in the 80s subcultures will fondly remember EN for making a lot of noise. Literally.
Nowdays they have calmed down a bit, due to aging I reckon.
Dutch music comedian Hans Liberg did a GG pastiche in one of his solo programs. I still owe the list a link of said performance and shall let you know once I found it.
As I have said GG rererences in pop culture are rare. Which I find strange, GG would be a perfect subject to be adopted by pop culture.
