Rated 6/10
It's fine. I think it started out strong, then sort of got a bit boring in the middle. it picked up a bit at the end, but I was kind of over it at that point. It's not really my kind of music, so an hour and 20 minutes is a LONG time.
A bit of a fun fact: Apparently Huey Lewis, who would later achieve fame as the guy with all the songs in the Back to the Future movie, was part of the backing band or something. He got a call out for playing harmonica. This is definitely not Huey Lewis and the News-style music.
Anyway, 3 out of 5 seems about right.
