I got to thinking about this because of Tio Toad's comment but also because of an interview I read with Brandford. Most of the time, when they play live there are no amps on stage and also no monitors. He's big into jazz being acoustic music. There is pa involved but mains only meaning it just takes what is happening on stage and makes it louder for the audience.
...yes, you can clearly see Jeff Watts "adjusting"...
I've seen that band many times over the years, and they always had monitors. (In fact when Bob was on the band I believe he had 2 just for himself...AND a plexiglass screen to shield his mic from Tane!)
I saw them here a year or so ago, and Eric's bass was LOUD in the mains...great, but loud (sounded like Mingus!)
