1. This goof is really to be expected, though at the time, I doubt that anyone connected with the show thought it would be. Sometime around episode 9 "Hell is Other People," the stage setup at Bimbo's changed somewhat The set seems to have been made larger (wider, more than anything,) blue neon light tubes were added to Kenney's drum platform, and a Persian-style rug was added to the floor in front of his kit. Unfortunately, the scenes
in this episode that featured Art Alexakis, Green Day, Stephan Jenkins, and the Goo Goo Dolls were all shot when those artists were on the set filming their individual episodes. (Basically, none of the artists who'd appeared on the show previously were brought back to film their scenes for the season finale. This also explains why none of these many acts are seen anywhere backstage during the show.) The Bimbo's set for those performances is as it was for those earlier visits. Gavin Rossdale's and Trisha Yearwood's appearances on the show were after episode 9 "Hell is Other People," and the Bimbo's stage set is seen in those scenes in its updated state. Cases in point...
During Bush's performance as the concert opener in this episode, Chris makes an effort to kick a bucket (which came out of nowhere...) to catch rain from the leaky roof, right up next to his microphone stand about
halfway through the song. The bucket is not seen again, even after five other musical acts perform there, until Chris and the band close the show with "Two Hearts."
Art Alexakis' performance right after the opener with Bush shows a distinctly different set. This is contrasted sharply because it's sandwiched between Bush and Trisha
Yearwood's performances – the only guest performances for this episode that were filmed on the new set.
Green Day's stage set is also exactly as it was for their episode, and it's interesting to note that they were the only visiting group to ever fully replace the usual Silvertone setup on stage. Kenney's drums are gone from the platform, in place of Tre's kit – exactly as it was in their original episode...
Finally, the only concert performances that include the carpet on the floor (aside from scenes of Chris and Silvertone alone,) are the performances with Bush and Trisha Yearwood.
2. After Chris and Anson make a valiant, if ridiculous effort to patch up the roof at the club, the next scene is a front-view of Bimbo's with a small crowd of people standing outside the venue as the rain continues to fall. Unfortunately, one of the cars we see driving up the street past the club is a convertible... with the top down...
3. Again after the roof incident, Chris and Anson are back on stage; with remarkably dry (and well styled) hair for having spent several minutes traipsing around on a roof during a storm...
4. As Chris' elusive Lieutenant leaves the concert, she apparently puts a note on the windshield of Chris' car. How she knew the Nova was his, wasn't explained.
As Chris holds the soggy piece of paper with the smeared number of his elusive Lieutenant, his mom approaches to say good night to him:
Dr. Isaak: "You should be so proud of yourself."
Chris: "I should?"
Dr. Isaak: "Yes, you made so much money for the Center tonight. And you had the guts to get up on that stage with all those talented musicians."
