    hey all,

    this is a question that has wandered through my mind many times and I
have never looked up a definitive answer.

     legally, does an artist have to obtain permission to cover another
artist's song, whether live or on an album?  What other legalities are 
there
surrounding this issue?  Are there any online sources where I can look up
this sort of info?

    thanks a bunch,
    mike
