I honestly don't believe that any of these newer, current bands you guys are mentioning have ANY staying power what so ever. They too will be thrown on the trash heap of forgotten musical groups (Joining Glass Tiger, GTR, Dexie's Midnight Runners, and more), thus requiring yet another re-theming.
Here's a though...I'm sure the modern technology would allow for "Randomization" (Think Star Tours). Every few hours, the superimposed rock band in the pre show recording studio can change. The accompanying music in the train would match the band. So, you've already got Aerosmith recorded. Get great bands like AIR SUPPLY, STARLAND VOCAL BAND, PABLO CRUISE, LITTLE RIVER BAND ,etc. In there to record a pre show and...BAM!
Instant classic that will transcend generations for decades.
