With the Bee Gees it's all about harmony...they do a great job mixing in the three different brothers. Immediately i noticed how the sound engineer made it so that the musicians were more of a background group to the singing, which is how it should be. Their replication was almost flawless...can there be a better Bee Gees group than this? I would be surprised. Strange how at 68 years old I was the probably the youngest person in the audience. When i go to rock tribute shows many different generations are represented...not with this group. I would have liked to have seen some clips from Saturday Night Fever or clips from that era in the background (especially this song)...there wasn't even a Disco Ball.
