This video has been restored to my best ability using QTGMC+, probably the highest quality deinterlacing method we have. Color & contrast has been restored, 60fps displaying both fields correctly. Upscaled to 4K to prevent as much compression as possible.
Audio was restored using Reaper. Ran through several audio processors to boost certain instruments at certain times, then master bus processing was applied to keep levels consistent and clear.

Green Day's live performance of "Waiting" on Jay Leno. From the 2000 album Warning.
