Tribute bands on autopilot

I’ve seen Brit Floyd three times and was impressed each show.   Great performance and tickets of course are considerably cheaper versus a Waters or Gilmore concert.   Recently attended a Fleetwood Mac Tribute band that was also legit.   I do have one observation.   These bands go from city to city doing the same gig.   No new music to change things up like real bands do over time.  So while technically the shows are solid there seems little passion.   The band is on autopilot so to speak.  I know if I had to go year to year basically playing the same core set of songs I’d go bonkers!!!!
