I had to re-post this here. The quality is very good (is YouTube FINALLY becoming a watchable medium?) and I have never seen it before. It gives a rare glimpse of Slam Stewart's late-40s trio that featured Beryl Booker on piano and vocals and John Collins on guitar. Stewart had previously been a member of the Art Tatum Trio with Tiny Grimes, which, like this combo, showed the undeniable influence of The King Cole Trio. In fact, it's hard to really grasp how influential The King Cole Trio were at their time. This clip was taken from the 1947 film, "Boy! What a Girl" that also featured musicians such as Big Sid Catlett. If you are interested in the trio check out this site.
