Identification caveat. This event documents Modeste Abdallah Guillaume / G. M. Abda'llah as named in the source. Whether that man is the "Abdullah" Neville Goddard described as his teacher is not settled — see documentation/ABDULLAH-DISPUTE.md. Per the governing rule, neither the identification nor its rejection is asserted as fact here; a null verdict is a legitimate outcome and a wrong identification is worse than none.

OCR explicitly states this is Guillaume's first time appearing in concert in Pittsburgh -- a discrete, notable happening. No existing 1911 event (photo publication #934, Walker's death #1490, 1910 census/relocation #705/#706, 1912 items) covers a Pittsburgh concert debut.

Direct clipping text (node:4095): review of the recital at 'Warren church last Monday evening', with a repertoire from grand operas including French numbers; states plainly 'This is Dr. Guillaume's first time to appear in concert in Pittsburgh'. Miss Writt, Mr. Arter and Miss Pryor also performed; credits 'Dr. Virgil and the tireless workers of the Busy 20 club' — tying this recital to the Busy 20 Club/Warren M.E. Church booking documented in hist_event 1685 (see merge proposal). A further independently scraped copy (node 4121) confirms the wording; no additional dating information.
