Don's son, Dean, produced this video to be shown at a tribute concert.
Elliott played trumpet, mellophone, and vibraphone in an episode of the television program, The Subject is Jazz that aired on May 24, 1958 at 5PM (more info). The group in this episode also included Lee Konitz, Billy Taylor, Warne Marsh, Mundell Lowe, Ed Safranski, and Ed Thigpen.
There are also several videos of Elliott as a vibraphonist with the George Shearing Quintet.
"Conception" - Elliott has a vibraphone solo.
"Swedish Pastry" - Elliott has a solo at 1:09
"Move" - Elliott has a solo at 0:59 (Compare this to the above video of "Geneva's Move")

"I'll Never Smile Again" - starts at 9:43 - Elliott does not have a solo
Don Elliott plays mellophone in this video. You can only see him for a few seconds, starting at 0:45. For a much better recording, see the DVD, "Jazz on a Summer's Day" (http://www.amazon.com/%C3%82-Mahalia-Thelonious-Washington-Mulligan-Armstrong/dp/B00003OSU4).
