Well, from my perspective, all the arrangers sounded great, and none, at least to my shot to Hell hearing, sounded significantly better than the other. And, to perfectly honest, at least from the way I look at this industry, the vocals are the most important item to consider with any arranger. The keyboards ALL do, and DID a great job of providing excellent accompaniment to the guys singing the songs. And, our audiences demand great vocals. By and large, they could care less about the accompaniment behind the vocalists, hence the popularity of Karaoke, backing tracks, midi files, etc...
As it turned out, AJ is one Hell of a good singer as well as a player.

I am not putting down ANY of the boards that were at the jam because they all DID sound good, but Gary, I LOVE YA MAN, and you are entitled to your opinion, but with all due respect my friend, if you didn't hear a MARKED difference in the Ajamsonic, then:
A)you were out grilling some of that great food you prepared for us; or
2) you had one too many Green Margaritas

...
Now Gary, I'm just 'rattling your cage' a bit, but seriously, I DID notice a marked difference ... How about the rest of the members who were there - am I alone in my judgement???
And, yes, vocals are a major part of our performances, but many of us like to play some instrumentals during a song, much like we hear on a record, and I think the Ajamsonic voices - such as the sax - would add considerably to that part of a performance especially when playing in other than an assisted living environment ...
