Apparently these two were great friends.

" George Beach enjoyed a close friendship with one of the top English tournament players of the day, Joseph Henry Blackburne, known as “the Black Death”.

Blackburne described his friend as “certainly the finest amateur player outside London”. The two men played many games over the board. They also played many without sight of it as they travelled by horse-drawn trap or tramped the countryside over Kinder Scout and the neighbouring hills during Blackburne’s frequent visits to stay with Dr Beach’s family.

Each of these visits lasted about three months: as long as it took to consume a barrel of home-brewed mead produced by Mrs Beach. Then Blackburne left! This friendship led to the master giving a blindfold exhibition at the Macclesfield Club in 1900."

<Mr. Blackburne, undoubtedly the greatest living exponent of blindfold chess says of this game: "It is the most brilliant and interesting that I ever lost in blindfold play." Dr. Beach is the father of the Rev. G. C. Beach, Norfolk and Norwich Club, and the game is a fine example of his skill. Played at Macclesfield, January 8th, 1900.>

Blackburne gave more blindfold displays than anyone, that and normal simuls was a major source of income.

Would not be at all surprised if one or two exhibitions or the Beach/Macclesfield connection fell through T.D's. net.

<"This friendship led to the master giving a blindfold exhibition at the Macclesfield Club in 1900.">

I've no doubt at all the Macclesfield display happened, sounds like a private affair possibly for club members only and was therefore unofficial, not advertised, no mention in current chess mags or main chess columns.

Blackburne gives 157 blindfold games in his own book. But the book was published in 1899, just before the time we are interested in.
