Learsfool, that was a very thought provoking article. Most people prefer words with their music, we're the ones who are different; however, in the case of jazz, musicians feed off of other musicians, there were many more jazz musicians in the 50's and 60's than now. I'll give you an example; I just picked out two of my favorite albums: Benny Green, "Soul Stirring", consisting of highly prominent sidemen who are stars in their own right: Gene Ammons, Sonny Clark, and Alvin Jones were jazz stars who also led groups. Art Blakey and the Jazz Messengers consisted of so many stars down through the years to even include Wynton Marsalis, that the jazz had to be top quality. The album "Moanin", consisted of Lee Morgan, trumpet; Benny Golson, tenor sax; Bobby Timmons, piano; and of course Art Blakey on drums. When just two LP's are loaded with so many greats, the music couldn't go wrong. Back then, people who were into popular vocal music, had a few jazz LP's because they liked the music.
Although these tunes came into my collection without vocals, here are some with vocals on youtube.

Enjoy the music.
