nic,
in the concert browser, the july 14, 1993 gig at the meadowlands in new jersey has '???' listed as the venue, but the august 14, 1993 gig in east rutherford, NJ has 'brendan byrne arena' listed as the venue. the brendan byrne arena is the venue at the meadowlands (which is the name of a sports/concert complex in east rutherford, including the arena and a stadium). could they be the same venue? can't think of any other meadowlands venue they could have played in twice....
hope this post makes sense! :D
