Two friends said I had to see this. It was the best show in Vegas. One friend had already seen in 3 times (note, we all get free tickets).
I'm glad I went, but I don't think it topped Human Nature (and I'm not a Motown or boy-band fan).
What's good about the show? 6 musicians (the 4 leads plus bass and drums) playing and singing live. Go see that!
What's wrong with the show? To create a story line, they don't always finish songs which is annoying. Also, there's characters doing asides to move the plot forward. The plot feels contrived, and is unnecessary. And it slows the show down.
Yes, the Jerry Lee Lewis performer does steal the show, but the show is written with that in mind. The musician playing Carl Perkins held his own, playing a solid guitar.
The addition of the female character was smart, adding a nice contrast in voice and view to the show.
It's simple: if you like live music, it's a very good show once you get around the forced dialog.
