Nirvana's Krist Novoselic performed an accordion version of 'Sweet Child O' Mine' alongside Guns 'N Roses' Duff McKagan last night. Watch it below.

McKagan recently released his advice book, How To Be A Man (the title of which, he insists, is tongue in cheek), and held a release party to celebrate last night (17 May).

During the event, he teamed up with Nirvana's Krist Novoselic to perform a vaguely recognisable instrumental rendition of 'Sweet Child O' Mine', with Novoselic on accordion and McKagan on bass.

How To Be A Man (And Other Illusions) is McKagan's second book, having previously written the autobiography Its So Easy (And Other Lies). This one is inspired by the Seattle Weekly column he wrote for five years.

McKagan has also released a three-song EP, also titled How To Be A Man, which acts as a companion piece to his book.
