Multiple copies are GOOD
In a computerized world it is EASY to lay down multiple "windows" side-by-side and compare.
The morning that the request for "East Of Woodstock...etc" came in...my transcription was the first on the net (from an Entertainment Weekly copy) - OF COURSE there were errors (that is one way sites can locate material that was stolen from them)....I clearly heard "coke fires" (which makes sense) and the "artist" writes "cook fires" (which makes sense)....Oral Tradition.
You might say that the fall all began with Guttenburg....but .... I will need to check my college lecture-notes .....Demosthenes??? criticised the advent of writing because people would become "lazy with their minds - when they no longer had to remember."
Thanks to references from the Mudcat authorities - several "primary sources" (actually secondary) have fallen into my hands....I am hard pressed where to start additions....but "if you have to swallow a frog...do not look at it too long...if you have to swallow more than one frog ...start with the biggest first.)
The advice that a "midi" included has been one of the hall-marks of the DT included....lyerics alone are a dime a damsel.
