Billy Corgan is a longtime pro-wrestling fan and occasional promoter. And last year, TNA Wrestling, probably still the second-biggest American wrestling promotion, hired Corgan as a Senior Producer, Creative and Talent Development — a writer, basically. Tonight, TNA’s Impact Wrestling TV show, which has bounced around between cable channels in recent years, will start a new stint on the Pop network. And Corgan won’t just have a hand in the show’s storylines; he’ll also be responsible for its sound.

Yahoo reports that TNA is using an unreleased Corgan instrumental called “Roustabout” as its new theme music. Corgan wrote the music for some other project, but he ended up giving it to the show. Talking to Yahoo, John Gaburick, TNA’s Senior Vice President of Television, says, “Billy and I were discussing creative elements for the show when he suggested the song and presented the opportunity to use it on Impact Wrestling. To be able to use an unreleased Smashing Pumpkins song is awesome and sets a commanding stage as fans tune in every Tuesday.” The song is a fairly generic piece of instrumental synth-work, and nothing about it really identifies it as a Corgan song. But the show’s intro does succeed in making me want to watch wrestling, which is really the whole point of the thing. Check it out at Yahoo.
