The Smashing Pumpkins launched their new album Monuments To An Elegy with an epic show at Koko in London Friday December, 5 - with a little help from Marilyn Manson, Gigwise reports.

Earlier, Manson told Gigwise that he hadn't seen friend and Pumpkins frontman Billy Corgan for 15 years until last week - and that he'd been in rehearsals with them. All of that came to a head with the pair united on stage (along new touring Pumpkins members Rage Against The Machine drummer Brad and Killers' bassist Mark Stoermer).

After an already mind-melting show, Manson stalked on to the stage to perform an encore of his new single 'Third Day Of A Seven Day Binge', before kissing Corgans' bald head and launching into an awesome rocked-up version of Pumpkins' classic 'Ava Adore'.
