Somebody may be able to correct me on this but my recollection is that John Kirkpatrick's very first LP included a Bach Fugue played on an Anglo, in a successful attempt to demonstrate that the then popular belief (that English Concertinas were the only concertinas worth learning because Anglos were only "toys") was incorrect.

The first time I witnessed Flight of the Bumblebee played on an accordion was in about 1965, when a touring Russian played it at the Dallas Brooks Hall in Melbourne. Again from recollection, it was a piano accordion miked internally and with a 'free chromatic bass'. It was the latter revelation that helped stick the event in my mind, along with the effect of a bee buzzing around inside the instrument.
