On page 26 of issue #34 (Summer 1996) of Dupree's Diamond News, Dick Latvala stated in an interview "What I know exists in our Vault are the shows, and they are on four-track 15 i.p.s." and "There are two dates, 10/28 and 10/29, both of which have four reels."

Mickey and the Hartbeats, October 28, 1968, Matrix, San Francisco, CA
Deadlists no longer lists (if it ever did) a Hartbeats show at the Matrix on Monday, 10/28/68. It doesn't appear on the Chicken on a Unicycle Matrix list, either. But what are we to make of this tidbit, from Deadlist's 10/29/68 Hartbeats entry?
