As other reviewers have mentioned, this is the bonus disc of a 2 disc set (the "other" disc contains the concert).
Wouldn't be so bad if when you submit "U2: Zoo TV Live from Sydney " at the site search, you were given a choice of two discs, etc. The "Main" disc (with the actual concert) does not seem to be available. What..was there only one copy and somebody lost it. How is this possible?
