Although I love Joey and technically he can play circles around Groove Holmes, this is just a (very well played) take on the 'hit' Groove Holmes arrangement. He even uses Groove's solo voice in a lot of the tune. So yes, I agree it's good listening if you're into jazz organ or just a fan of Joey's great playing (like I am), but for some reason, if it's not presented as "here's Joey D. doing a great take on THE Groove Holmes hit arrangement of Misty", that it's a little bit mis-represented. It's a little bit like plagiarism (rather than a cover), as many non-jazzers may not be aware of the original.
But yes, it is a "refreshing morning listen". In terms of talent and playing ability (but not necessarily originality), I think Joey D. may be the best JAZZ organist of them all. JMO.
