music from the movie

In the scene where Christopher Lloyd is flying along in that rickity old plane he drops a cassette in the player and starts listening to what I can only describe as Japanese Tea Room music, it's great, can anyone tell me where I can find that music. It's not listed in any of the articles I've researched on the movie, and when I search the web for Tea Room Music, I get a million hits on Tea Rooms that have music. Arrrgggghhhhh!!!!!!!
