This is 100% pure music right here.  I cannot add much but some interesting tidbits.  As a bassist, I have read interviews with Tommy Shannon.  In one he was asked if her remembers any particular gigs.  He mentions one that nobody could possible remember (1987 in Boston or something random like that) as feeling, "as though we had all day between the beats to play."  The interviewer asked him if he remembers anything special about the EL Mocambo show...."Nah...that was pretty much just another show in 1983...they were all pretty much like that back then."
