If you don’t know Randy Rainbow, that means you haven’t seen his hilarious parodies on YouTube. And you haven’t heard him interviewed on NPR’s “Fresh Air.” And you haven’t read the profile of him in The Washington Post.

In any case: Google him now.

Rainbow has rocketed to comedy stardom thanks to how he rewrites lyrics of showtunes so they become political parodies. How clever are his lyrics? Well, his fans include Stephen Sondheim.

One of the first big impressions that Rainbow made was with his version of “Supercalifragilisticexpialidocious”; it was a Trump number called “Super Callous Fragile Egocentric Braggadocious.” His many other reimaginations include morphing Madonna’s “Borderline” into “Border Lies,” and “Maria” from “The Sound of Music” into “How Do You Solve a Problem like Korea?”

He creates faux interviews, too, where he splices himself asking questions into video of real figures answering queries from other reporters.

Rainbow brings his satire to the Garde Arts Center for a show on Friday.

And, yes, Randy Rainbow is his real name. He was clearly destined for a life in showbiz.

Randy Rainbow Live!, 8 p.m. Friday, Garde Arts Center, 325 State St., New London; $35-$55; (860) 444-7373, www.gardearts.org.
