I saw a show on this tour about a month before the monster 101 show you were at. Other than the massive DM cred for being at the most famous show in the band's history, they were almost the same setlist.

Looks like you got People Are People and we got Martin's solo cover of Never Turn Your Back On Mother Earth.

I was a fill-in too! A family friend who is 3-4 years older than me was going with all her friends. They had someone cancel and she asked if I could go. My parents didn't want me to go, but she talked them into it. It was only like the 5th or 6th concert I had ever been to and the first big show like this. Her friends all ignored me, but I was in heaven and was really the only one of them that knew every song.

I got into DM right as Black Celebration was coming out by buying Some Great Reward (based on hearing PAP on college radio) from the discount bin at Camelot. I managed to find the 3 older albums in those bins along the way. As well as Erasure and Yaz.
