You wanted Billy Corgan to play old-school Smashing Pumpkins songs? You got it.

During a recent stop on the band's all-acoustic In Plainsong tour in Pittsburgh, Corgan ripped through the entirety of Gish, the band's 1991 debut, in about three minutes. Granted, he only played the first few seconds of each song, but it seemed like more than enough to satisfy the crowd, heard in the background of the fan-shot video.

"It's amazing how many songs have to do with LSD, now that I think about," Corgan said near the end of the medley. After that, Corgan ripped into "Geek USA" from 1993's Siamese Dream.

The Pumpkins have five more shows left on the acoustic tour -- their first ever -- before joining Marilyn Manson on a tour that will take them through the beginning of August and across the U.S.

Last week, news broke that Corgan had replaced Pumpkins drummer Brad Wilk (once of Rage Against the Machine) and bassist Mark Stoermer (of the Killers) with Robin Diaz and Katie Cole.
