O'Horgan, the only Broadway director to have four shows running concurrently on Broadway, is in the middle stages of Alzheimer's disease and is holding the sale, which will partially benefit the New York City chapter of the Alzheimer's Association. The Nov. 3 sale will take place in O'Horgan's Union Square loft and will include such items as a painted gong from the final scene of the original Broadway production of Jesus Christ Superstar; an authentic Dulcitone – one of only 2,000 ever made; and several complete families of woodwinds and recorders from around the word.

One hundred percent of the $25 admission fee and twenty percent of the total proceeds of the sale will benefit the New York chapter of the Alzheimer's Association. O'Horgan has organized the sale to benefit the organization, which has supported him during his illness.

O'Horgan was Tony-nominated for his Broadway directorial debut with Hair. His work for the Broadway stage also includes Lenny, Inner City, Dude, The Leaf People and Jesus Christ Superstar.

The Nov. 3 sale will take place from 11 AM – 4 PM at the home of O'Horgan. Because it is a private residence, organizers request that interested parties phone (866)-500-3279 for reservations and address information.
