Interesting.
Because the sound was good, this may have been why the Tulsa gig was a choice show of McCartney's current tour and maybe one of the best of his solo career.
(I know, I know ... but I checked a Macca fan board after the show, and quite a few longtime fans said the Tulsa gig was the best they'd ever seen from him.)
It seemed like the band was really locked in, and maybe it's because they could hear themselves and the audience's responses really well.
Absolutely....you could feel the interaction between the band and the crowd....they fed off each other. That's what rock and roll is all about. It's the feel a concert goer yearns for! Bad sound interrupts that chemistry as does a lousy audience or a poor performance.
