There are some
great JM shows streaming here:
http://tela.sugarmegs.org/alpha/j.htmlThese can also be saved (but they come out as one track and would therefore need to split into tracks using a program such as Nero).
Be sure to look for shows under both "John Cougar" and "John Mellencamp", however.
There's a really clean tape of the live recordings mixed by Don Gehman on JM's birthday in '87, for example, that sounds waaaaay better than the "Little Bastard's Birthday Party" boot I've had for years; the interview segments are complete, also.
