I really loved the short video of Dick Hyman with a piano and the System 55 that was released recently! 
Is there any way at all to get the audio from this clip? Or perhaps it will be released in some way in the future?
You can find the video on YouTube https://www.youtube.com/watch?v=UHHN38_oEsw
From here you can download it with a tool like ‘Free YouTube Download’ and extract audio with a tool like ‘Reaper’
Great! Thanks for that I will give it a try.
EDIT - It worked perfect - could even choose to just get the audio file
