I have copies of several Geoghegan sheets, by various publishers, but none of them are by B Williams. The publisher of C&M is D'Alcorn and the Yorkston C&M is Francis & Day, at least my copies are. Some songs were published by several publishers of course. I think some of Harry Clifton's were published by both Metzler and B Williams, but of course the majority by Hopwood & Crew.
