I met Roger Waters before a gig in Chicago and he signed my "Animals" and "Wish You were Here" LP's for me and I got a picture with him.
Tried to meet David Gilmour in Chicago as well, but he didn't show up but I met his wife Polly Samson and she signed her book for me as well as a copy of David's "rattle that Lock" LP since she helps David with some Lyrics.
