Perhaps we can all put our heads together and identify some of the musicians in this short film! Please send the link to this post to your friends in their 70s (contemporary with Itzhak Perlman, who is easy to identify) and 80s (I will too). Put your identifications in the comments, and make sure to give the time location in the film. Ready, set, go!
UPDATE: I have some identifications! The "headless" coach is Josef Gingold. James Buswell is the first violinist in the quartet (the one with THE BOW ARM), and Sarah Johnson (sister of BJ Johnson) is the violinist playing the Mendelssohn.
