Query: Ok concert but these guys are getting old and their music is not up to what it used to be.

An ok video for the concert lover but these guys don't sound anywhere as they did say 15 years ago. If your looking for concert DVDs from the 70s and 80s get the Doobie Brothers, STYX or REO Speedwagon which all are better and their sound is better with age.
