The Smashing Pumpkins just put out a new album, Monuments To An Elegy. The had a show at Koko in London on Friday night with a special guest Marilyn Manson.  Manson came out during the encore to perform his new song “Third Day Of A Seven Day Binge” and join the band on “Ava Adore.” Manson told Gigwise that he had been rehearsing with the band all week, and that it was the first time he’d seen Billy Corgan in 15 years. (Last year, Manson told Larry King that Corgan was mad at him ever since he said it would be a good marketing idea “if [Corgan] sold Charlie Brown T-shirts and bald caps at concerts … He does look like Charlie Brown a little bit.”) Watch below.
