This isn’t remotely tech-related, but it’s definitely Retro.  I found this on YouTube recently and have to say I love it!

Quite apart from the musicianship, look out for Pat Metheny displaying his usual facial contortions, and Lyle Mays looking for all the world like the carny from Despicable Me!

Sadly the DVD this was ripped from (More Travels) isn’t easy to get hold of now.
