Jim: For 2/24 and 2/26 1970 you list the band as "Mickey And The Hartbeats", but the articles in the newspapers say: "Mickey Hart and the Heartbeats" Could it be listed as the way it was in the newspapers and not what name people refer to them as?
Also, you say: "Sorochy notes that generally the Matrix books band for a run of shows". Could you changed the spelling of my last name to add the "T" (its t-y) and say "a band". Details, details... :-) Dave S.
