A lot of people these days know Wayne Brady from his Fox television karaoke show "Don't Forget the Lyrics" but while there is audience participation it doesn't involve them singing. Instead, the focus here is on the kind of improv that Brady did every week on the Drew Carey hosted "Who's Line Is It Anyway?" that ran on ABC for years (and still plays on ABC Family in endless repeats).

With a crack band, back-up singers and dancers, and fellow improv comic Jonathan Magnum, Brady keeps the laughs rolling with a series of made up on the spot sketches, games, and songs many of which involve dragging unsuspecting audience members into the spotlight.

For example, he brought one woman up on stage and asked her what she did for a living and to give an example of a situation from her work life. Turns out she was a Federal Agent and told Brady about the guy she busted who was trying to smuggle ecstasy into the US in his adult diapers. He quickly turned that into not only a sketch but an entire musical number and proved that he is funnier and faster on his feet than you and I will ever be.

Brady uses many classic improvisation games like "Human Props," where audience members are asked to be the inanimate objects in a scene (doors, cars, seat belts, etc.) and "Sound Effects" where they have to make all the noises (opening a bottle, jumping in water, grilling meat). The fact that most of them can't keep up is where most of the humor comes from and he merely steps back and lets them make big fools of themselves, in a good-natured kind of way.

But it's the songs that are the most impressive pieces of the show. Get two middle-aged men on stage - an accountant and a financial advisor - and he immediately creates a rap battle between the two, complete with rhymes and choreography. Audience suggestions of a singer and a made up song title inspire instant full-fledged numbers out of thin air, all of which are laugh-out-loud funny.

Of special note here is the band and his back-up singers who somehow manage to keep up with every spur of every moment at break neck pace.

Brady is also an inspired mimic. His Prince was spot-on and the show closer - a series of real songs from the likes of Sam Cooke, James Brown, and Sammy Davis Jr. - were a delightful blend of impression and homage.

Making It Up is, in many ways, a throwback to classic Vegas variety shows, with singing, dancing, lots of laughs, and a general sense of genial fun. The fact that it'll be different every time you see it means it's a show you could go to over and over again.
