I remember seeing this show on TV when first performed. I was impressed then, I'm still impressed now. Naturally, a person's voice will lower in register with age, so it should come as no surprise that Barry and the Brothers Gibb don't go sky-high in their harmonies as they used to. That said, they still have a three part harmony that's just beautiful and unique in all of pop music. Their unique vocal harmony and chemistry are front and center here,as they go through four decades of song, both their own hits and songs written for others. This show was performed and taped at the MGM Grand in Las Vegas, and the crowd seems a bit dressed up for a concert, but I guess they were dressed for a night out. The sound quality on this disc is fine, but I had to turn the volume higher for this show than on other concert discs I have, so perhaps a move up to DTS wouldn't be a bad idea. The picture quality is fine and razer-sharp. I don't think they left any song in their catalogue out, even having Andy Gibb, sadly departed, "Guest" in a beautiful quartet,"Don't Throw It All Away". Celine Dion appears as well, in "Immortality", and they sound so GOOD together one wonders why they haven't done more together since. Of course, all the "Saturday Night Fever" songs are here, and they are wonderful. All in all, this is a fantastic show, very straight-forward, with no gimics or flashy stage show to distract form the incredible three-part singing that is the hallmark of the BeeGees.
