This is understandable, of course, for those of the 1930s and before. It also is true, unfortunately, of some later musicians, particularly in jazz.
That’s to say that I couldn’t find any video of composer, arranger and pianist Tadd Dameron. Here he is with two other giants: Above is “Dameronia,” with Fats Navarro. Below is “On a Misty Night,” with John Coltrane.
Here is Scott Yanow’s profile of Dameron at AllMusic.
