Post script. After I wrote the original posts, I had a couple of other recollections I wanted to add.
Around the time of my trip to NYC, when we sang along with Dirty Boulevard, a few friends formed a band called the Despondent Astronauts and played local venues in Adams Morgan and the emerging U Street corridor. They did a few VU covers, including Pale Blue Eyes and Femme Fatale as we followed them around back then.
During the U2 Zoo TV tour (in 1992, I think) - this is the stadium tour where they'd brought along all the East German Trabbie cars as part of the stage set - Bono sang a cover of Satellite of Love. He was out on one of those islands they create to get the band closer to the crowd, and suspended above him was one of the trabbies. He took a rope that was attached to it and gave it a spin - so the satellite above remained in orbit for the rest of the song.
