Never let it be said that Billy Corgan and Marilyn Manson didn't go all out to give fans their money's worth with their End Times Tour this summer.

As you can see from the fan-shot footage here from their tour-concluding Aug. 9 stop in Nashville, the duo seemed to be having quite a bit of fun on the road; during this clip, Corgan makes his way out onstage during Manson's performance of "Antichrist Superstar" — dressed as a nun, no less — and joins him for a version of the song that concludes with a fairly unorthodox version of Cyndi Lauper's "Girls Just Want to Have Fun."

Covering "Girls" was always a part of the End Times plan, as Corgan and Manson divulged during their joint press conference announcing the tour. "I believe in the annals of history, he has a better idea of what girls want for fun than I do," joked Corgan, to which Manson quipped, "You mean in the anals of history?"

Corgan, fronting a new Smashing Pumpkins lineup that boasts the return of drummer Jimmy Chamberlin, has been touring behind the band's recent Monuments to an Elegy LP, which peaked at No. 33 upon its release last December. Manson, meanwhile, is on the road in support of his own latest effort, The Pale Emperor, which hit No. 8 after arriving in stores this January.

With the End Times Tour wrapped up, Corgan will be offstage for the foreseeable future, while Manson now looks ahead to Japanese and European dates scheduled for the late summer and fall.
