Accordion Sweet Child O'Mine

Do I smell a new two piece?

Duff McKagan of Guns N' Roses is out promoting his book 'How To Be A Man'. Normally book tours are pretty boring, but when he stopped into Seattle on the tour, he had some friends with him. Mike McCeady of Pearl Jam was there to announce Duff and Nirvana's Krist Novoselic, and Krist came on stage with an accordion, reports Loudwire.

Krist and Duff do a full on cover version of Sweet Child O'Mine complete with audience vocals.
