These are awesome Richard.
These are nice man. one of my favourite pictures of them singing, you can really hear them in this pic. I own a few csn autographs. My profile picture on here is of one I bought it at a crosby gig then asked graham if he would sign it a few months ago in oxford, he said to me you want me to sign Crosby's lyrics sheet, so i said you sing it pretty good together man hah. I think its pretty rare to have both on it, as croaby only signed 500 and sold them at his solo gigs on the sky trails tour in london. and this might be the only one with them both on it.
Graham almost signed it in blue marker witch would have been s*** haha
