Kabinopus, music tends to be both cultural and regional. The one exception might be 'Classical'. Truth is, this type of music wasn't heard in very many American households either unless they were middle-class African-American households. Plus, the heyday of Organ-based jazz was 60's to mid 70's where the dominant musical genre was Pop, R&B, Blues, and early Rock (Rock-N-Roll). So if you missed it, you're not alone . There's also the matter of 'Aquired taste' (if you were not born into it culturally). Some people never get it; the 'groove', the 'funk', the emotional overkill , and the whole concept of improvisation. These people are still clapping on the "1" and "3" .

Unlike most other types of popular music, Jazz Organ has ALWAYS made the bass line a prominent, sometimes dominant, part of the song. There's nearly as much improvisation in the bass line as in the solo. It's what sets the groove and is very much dependent on the rhythmic sensibilities of the organ player (and his 'spiritual' connection with the drummer). Sorry for going on and on, you just had to be there .

You're absolutely right about the 'old' tunes, though. They stay good because they were good to begin with. I'm grateful that so many great musicians strive to keep them alive (and fresh).
