I have the 45 rpm single of Swingin' Safari and while it is similar to the original video, the 45 is a much tighter sound.

The Yamaha well!
Not its best showing

The Audya
Good effort, but like all styles they are just too repetitive, and lack the free flow of the original.

Also don’t forget that A Swingin Safari style was featured in this recent Korg PA3x demo, which starts at about 2.15



What does this prove?
There is no bad keyboard, and no top keyboard, just that some people can play better than others, which in the end is what makes the performance. (Not the keyboard)

To add another version, here is one on a Wersi, which starts at 3.25



My opinion
