I discovered jazz ready to understanding it late in my 35 years forty years ago then...
But your post remind me that i bought a Louis Armstrong album where he sang also ... I was young in my 20...But for me this album was not a door to enter into jazz, it was Louis Armstrong as a unique artist so big (the sun) then, it was more than jazz itself for me at the times because no one else compared one second in my young heart to Louis voice and trumpet...It takes 15 more years for me to discover Chet Baker ( the moon) then and others jazz artists...
Marsalis describe well in 2 minutes what i felt without knowing it at the time :
