I remember being at the concert in Las Vegas.  It was a great night.  Now with only 2 remaining members it is also a great concert dvd.  I've always loved the Bee Gees.  I was not a fan of Disco but many people don't hear their songs before disco started and after disco ended.  I know I'm old enough to remember the Bee Gees before the 70's.  Great DVD if you want to hear a great DVD.
