I was there too!
Very cool event. The records were all random colors. Pink, purple, green, or grey. They sold out pretty quickly. I was there for about 4 hours but it was worth it. Wayne presigned some of the records with "inserted by wayne."
Since it was all random you didnt know what color record you had or if it was presigned until you opened it. I saw him sign the neil diamond record. He drew bushy eyebrows on the picture. I got him to sign my record and then he drew a big face on the front of the album cover.
Really cool guy though. He would talk to anyone about anything. Shows, new music, other bands, whatever. He was checking out all the other music people were buying in addition to the record. And on top of that, the record is pretty damn good.
I'll try and post some pics I took later.
