A little history lesson, if you please.
When Rick Derringer wrote & recorded "Real American" for "The Wrestling Album" in 1985, it was intended for the team known as the US Express, Barry Windham & Mike Rotundo. However, Hulk Hogan hijacked the song to make it his theme. As we all know, Windham, who later entered the WWE Hall of Fame, and Rotundo would leave for WCW/NWA shortly after the album was released in the winter of 1985-6. Rotundo would return first, adopting the guise of Irwin R. Schyster (IRS for short), a walking parody of the Internal Revenue Service. His two sons are in the WWE now (Bray Wyatt & Bo Dallas), while papa Mike pulls out his IRS specs and briefcase from time to time for nostalgia appearances. Oh, by the way, Windham is Rotundo's brother-in-law.
As for the Huckster, he's all over the video, miming on the bass, which is ironic considering he was a bassist in a Florida garage band before he turned to wrestling. Derringer, though, doesn't appear, and contributed one more song, helping announcer Gene Okerlund cover a Derringer solo classic, "Rock & Roll Hoochie Koo".
Here's "Real American", as produced by the now-WWE.
