.... "I seem to recall that in the mid eighties Swedish State Television broadcast a short animated film about Bix B. Do you have any knowledge of this and/or access to this film?"
I do not. Anyone?
I checked Svensk mediedatabas (the Swedish Media Database) at the website of the Swedish Royal Library and found that on March 6, 1987 Swedish channel 2 broadcast something called "Bix - en jazzlegend" (Bix - A Jazz Legend) lasting 27 minutes. No details given whether this was an animated film.
Now we must find a video tape ...
