Bingo!!

That sameness of description of the observed skills strengthens the case that the event was as described.

I don't know the Ogdon story, but there are credible accounts of Liszt's feats as well as those of Saint-Saens that have led to them being thought of as two of the greatest (if not the greatest) sight-readers ever.

Indeed, but Brenda Lucas in her bio of her late husband, reports sight reading abilities that may very well be on the level of S-S or Liszt.

Full disclosure, this bio has been highly criticized by one particular member -who personally knew Ogdon- on the Radio 3 message board. There is reportedly a new bio in the works, though I don't think that Ogdon's talent as a sight reader or as a pianist who could learn instantly will be questioned.

That bio is quite depressing because there's much description of Ogdon's mental illness.

Thanks BruceD for the explanation (Sellars: American Theatre Director)... I can just imagine that all the chaps will now be using that cunning "≠" symbol to disagree ... saves a lot of unnecessary woids.
