DESCRIPTION: Mark and Flip Britton along with John Knobler make up RK3, definetly the Philly areas PREMIER absolute best trio you will ever see. After watching CSN do S.J.B.E. on Woodstock directors cut last night, I thought Crosby, Stills and Nash should somehow see this, and what better way than YouTube. Guys, sorry the video quality is not that great but for a little cheapo camera and some editing this is awesome. Love You Guys, JB
