Reports from Boston are that Mayor is off to Ireland, he and others are lobbying for the band to play Fenway (100 year old baseball park in the city), likely for the convenience for business folk, the publicity, and "tourism" bump the city will get as everyone consults the tour list repeatedly.
Having seen a concert there, I so hope they pass -- even if it's more seats than the Garden and outdoors. We were led to believe that the next tour would include arenas, and be at least that intimate with some sort of Audio Video design that would leverage a venue smaller than a stadium.
Granted the intimate venues did nothing for album sales last time. Radio stations may play them if they tour lots and lots of stations, pal up to Seax=crest, etc, but since radio is so fragmented and teen oriented -- so what?
