Jazz Casuals videos

Has anyone seen the "Jazz Casuals" videos on youtube?  WOW!  They are absolutely spectacular;  the only (very minor) letdown is that Coltrane isn't interviewed (although the performance is fantastic).  But Rollins, Cannonball, and many others do talk.  They are brilliant all the way around:

Coltrane:  

Cannonball:  

Sonny Rollins and Jim Hall:  

Dizzy Gillespie:  

Brubeck:  

MJQ:  

Art Farmer:  


[Sorry if this has been discussed elsewhere;  I didn't see any posts about it.]
